I am about a week late from leaving this shop their review. I guess I have been too happy cruising, gassing it in my truck after the amazing work Steve had done to my truck. My flowmasters needed to be replaced since they were about 20 years old, I was referred to Steve's shop by my mechanic. When I got there he was such a cool guy, friendly and straight to the point. When you see the parking lot you will notice they work on a lot of classic beauties. So you know their work is legit. He has parts on display when you enter the office area. He checked out my truck and I told him I wanted it louder. So he booked me within a couple weeks which made me happy. So I dropped my truck off early that morning and picked it up in the afternoon. I started the truck up and it sounded really good. It had the rumble and just a clean install. I was happy. But I wasn't gonna know the real potential until I hit the freeway lol. I took off and I felt it wasn't loud enough. But the sound was still crisp and like a beast so it was hard to explain that I wanted the same rumble just louder. Well Steve went above and beyond. This man heard me out. First he asked me is it too loud lol he was surprised I said it's not loud enough. He wanted to make sure I was happy with the results which I told him I loved how it sounded just wanted it louder I wanted that V8 to roar. He told me "let me do some research." He called me later that day and found something special for me. I got the call to pick it up maaaaan I was revving my truck all the way home lol. I have had the biggest smile and feeling like my old self. Even other people have complimented me on it. You know I rev it when they say something. Thank you again Steve. If you need your mufflers done this is the go to spot for trusted legit work! read more

My classic car had a quick resolution to my exhaust issue, and it was completed quickly, and very inexpensively while I waited. Very happy with the service they provided read more

These guys NEVER fail to deliver on great products, timeliness, efficiency and all around a great group of people. I have used them for several cars over the years and just again today. Highly recommend them to anyone! I had them take out a stock muffler (out of most recent pickup truck a few years back). Sounds great and has an awesome rumble sound. I am having to move to the east coast with a friend and did not want that sound for 2500 miles no matter how cool it sounds. Soooo..I had a stock muffler added back and now all ready for the long drive. Thanks guys!!! read more

I found this shop accidentally while looking for a different shop. I do not trust mechanics easily (or much at all!) These guys were awesome from the start!! They took amazing care of my car. I didn't have an appointment but they got me right in. Their prices were on the low end of the "average range." For Bay Area, that is a great price!!!! Although I hope to never need another cat con, I would definitely chose this shop over all others. read more

Our son had his catalytic converter taken while at work. Once replaced we started looking into how to prevent it from happening or at least make it much more difficult. The cage they installed worked. Someone tried and was unsuccessful. I recommend this to everyone. read more

Upon arriving at West Coast Muffler, you'll notice a lot of cool old cars and new ones as well. There's always a good selection of classic hot rods, muscle cars, work trucks and new vehicles. This tells you that most anyone and everyone trust these people to work on their cars. And rightly so! I have taken a classic 1972 Oldsmobile Cutlass convertible, a 1985 Chevrolet Monte Carlo Super Sport, and my brand new Chevrolet Silverado to the good people at West Coast muffler. They have met and exceeded my expectations every single time. This business has been here for many years. I myself have been a customer for over 10 years. The owner/ operator Steve, is an honest, no nonsense person with a great work ethic and excellent manners. A rare combination! He is both good at his job and quite pleasant to deal with. When he tells you he'll have your car back to you same day, that's what he delivers. This is a busy shop with multiple lift racks, almost always full up. But don't be discouraged, they are cranking them out. And they are doing it correctly. You can bet on that! They offer multiple services and have earned a great reputation for doing so. I appreciate these guys, their work, and their prices. I'm confident you will too. I have recommended them to multiple friends and neighbors, who were equally pleased as I was. Honest and fairly priced mechanic shops are quite hard to come by. Count yourself lucky to have found one in West Coast Muffler. I'm looking forward to bringing my next muscle car in for some exhaust work. Thanks Steve and the rest of the gang there. Keep up the great work ! read more

West Coast Muffler - Car muffler Mini Cooper s convertible - Auto Repair Near Me - Concord, California

Went to start my old 2002 Acura last week, and it was suddenly making a loud exhaust sound, along with enhanced odor. Since I'm way over my teen years, I decided the sound was not a good thing, so I found West Coast Muffler here on Yelp, and it was only 2 miles away, so I gave them a call to check it out. I was told to bring it in the next day at 7:45, which was actually a good time for me. Got there right on time, and there were no other customers waiting, so the owner Steve put it right up on the rack and found a cut in the exhaust right before the catalytic convertor. Someone had tried to steal it, but got interrupted before finishing. He offered to repair it with a weld for $60 while I waited, which I gladly accepted. They found 2 more cuts, and fixed them too. I offered to pay more, but he declined. Everyone there was extremely friendly, especially Steve. We talked some while his worker was doing the welding, and I enjoyed the talk. I also like that I was able to go in and look under the car to see the damages, something a lot of shops won't allow. I needed an oil change, but they don't do that. However, he told me about a 10-minute oil change business down the street, so I got one there, and was home by 9AM with 2 good accomplishments for the day, costing me about $120 total. That's barely more than going to Starbucks! OK, I don't go to Starbucks personally, so I don't really know this for a fact, so don't quote me. read more

So impressed by the professionalism and the quality of service provided at this establishment. Steve, thank you for being quality oriented and so attentive to detail. The car looks impeccable. He installed tips to our car and it looks amazingly symmetrical. He demonstrated a special care for making sure the service was perfect. I really admire people who run their business with pride and integrity and with no doubt, Steve has been doing that. Admittedly, my husband and I are picky and very particular in our taste. We were not satisfied with our initial request and he was completely eager and willing to change the design. He was friendly and at no point appeared to be annoyed that he needed to work an extra hour on the Saturday before Fourth of July. As I said, impressive. Steve has most definitely earned our business from this point forward. Recommend his services with no reservations! read more

I took my 64 Chevelle here because Steve came very highly recommended by several friends. I took the car there for West Coast to complete my big brake install, which meant checking the system, bleeding the brakes, checking the master cylinder, etc. As well as some minor muffler work, After 2 weeks and a bunch of excuses I was called to come get the car. When I went to start it to check the brakes I was told that I would need to tune the car properly in order to get the proper Vacuum so that the booster would work correctly, which was a crock of BULL-SH%#. I was charged over $1000.00 bucks. The insulting part is that the brakes never worked properly until I installed a Hydoboost system myself, in the process of checking there work I found no cotter pins had been replaced on the spindles, fluid was the same that was in there when I dropped it off. Oddly enough prior to dropping the car off and during all of my updates, Steve and his wife were absolutely wonderful, once it was time to get my car they hardly had anything to say to me, especially the wife. This is very unfortunate being that I had looked forward to them doing work on my project. Needless to say I will NEVER recommend or do business with these people again. "THANKS FOR ROBBING ME" STEVE! thought you were a stand up dude. read more

I had my newest car taken to Steve because it needed some exhaust work. There had been a cat back exhaust system put on it that didn't fit properly. He put in new piping and fixed the issue where the piping was no longer hanging low. He also installed a brand new exhaust tip on it. It looks awesome. This guy is a real artist. I will never go anyplace else for exhaust work. read more

Couldn't be happier with my experience at West Coast Muffler. I wanted to upgrade the exhaust on my new Tahoe (make it louder, install black exhaust tips, etc.) and I know ZERO when it comes to working on cars. The owner Steve was super informative and incredibly patient with all my (countless) questions. He also ended up being the one to work on my install and took meticulous care to ensure it was perfect...it was like watching a surgeon operate! If you want good honest work done well, this is your place. read more

Steve and his team were phenomenal. He was able to find us a catalytic converter last minute- and the last one in California for my Motorhome which they no longer make. He even welded chains on it in the hopes of making it a little harder to steal next time. For all your exhaust system needs he is the guy to see. Mufflers, headers, exhaust leaks etc. He does great work and has a lot of very high end vehicles in his shop so you know the quality is top notch. Thanks boys! read more

I took my truck to West Coast Muffler to have the aftermarket CARB approved K&N CAI system installed by Steve. He had done a great job dualing out my truck. Once again he did not fail me. He installed the system and boxed the spare parts up for personal storage. This shop is very busy. Don't get butt hurt if they don't hold your hand while you question the work you want done. Tell them what you would like done. Drop off your vehicle at the agreed upon time. Come back when called to pick up your vehicle and be happy knowing the work was done right. Pay the man for his job well done then tell everyone you know or post your happiness to yelp. read more

I stopped by because I wanted to upgrade the exhaust on my M5. Spoke to an old white lady (sorry didn't catch her name) and told her what I was looking for. She says they are too busy to give me a rough estimate. Mind you no one was doing anything from what I could. Asked when would be a good time to stop by again and she replies in a very annoyed tone that she doesn't know. Told her bye and left. Go somewhere else folks. read more

Like others have said Steve and his team provided great service. I had the catalytic converter stolen on my car and I left a message with the shop. I had a call back within an hour and they welcomed my business and within a few days I was back on the road. what could have been a potentially pain, this shop was actually the bright spot in a rough week. read more

These guys were awesome. True customer service. I had an 8am scheduled appointment for a minor issue and they had me turned around in no time. They had started the day with a significant challenge and did all the right things. Never once did it impact the service I received. I will be back next time I have a need. read more

Visited Steve at WCM last week for advice on which muffler should be installed to quiet down my 1967 Chevelle with a Big Block motor. Let him know I had done some research but preferred a professionals advice. He steered me in the same direction I was going. He also advised me to purchase them online as it would be quicker. I used his advise and today he completed the installation. What a difference. His crew does impeccable work and I couldn't be happier. They went the extra mile to tighten up the sub standard work that was already there. This exhaust system will last the lifetime of the car. Thank you Steve and crew. The work you did looks fantastic. read more

Contacted Steve and left a brief message on doing some work done on my exhaust, next day he called me up and put me down for the day I had suggested in my message. I had a bad tailpipe and resonator with multiple holes from Wear and tear over years.

Hands down the best experience I have ever had with auto repair. In my experience you get quality work or quality customer service, if your lucky. Here I got both and was not asked to pay a thing until I was happy with the results and all on a hand shake. In my case I went in for a muffler repair then after hearing how quite that repair made my 6 cylinder I decided I wanted it to sound like 8 and got exactly that. I could not be happier and will tell anyone who will listen! read more

West Coast Mufflers is awesome, I purchased an axle back for my subaru and the flanges didn't fit. went to their shop in the morning while the line was out the door Steve was great and professional. I explained my situation and wanted them to install the mufflers and redo the flanges. Initially i was not given a quote because there was no lift space, but Steve promised that he can get it done by the end of the day. So i went in, had a chat with Linda at the Cashier's and she reassured me that Once steve gets it on the lift, he'll call me and provide all the info before working on my car. Sure enough, he called at 2:30 and I got my car at 5PM the same day. professional service and fun people all around. West Coast Mufflers & Tire is a gem in concord. read more

My Ford Raptor's exhaust spent several years on the east coast with their salted winter roads so it seemed to be having issues (loss of power, exhaust smell, rattling). I stopped in to see what new system they'd recommend and they told me it needed a simple patch job and a new bracket. I came back a week later they quickly did ther work and only charged me $60. The weld and new bracket look great and ther truck is running much better again. Great shop and one I'll use again. read more

I've been going to West Coast Muffler for many years, having had full brake jobs done, suspension work, and modifying my exhuast system adding Flow Masters. West Coast has always done me right. They have always given me a good price, and have done excellent work. The last job they did was putting Flow Masters on my Suburban with a 454, with two exhuast tips coming out the back. The worker spent so much time making sure each tip was lined up exactly where it should be, I was kinda blown away. He made sure each tip was positioned exactly symectrical with the other tip. And the truck sounds great. I get many compliments on it's sound and asking me what I did. On one occasion, I had just hooked up my 7,000 lb. boat to go on a 350 mile trip, and the master cylinder went bad. I called WC Muffler, and they got me in immediately, and repaired my truck, and I was out the door very quickly. We made the trip without any problems. On another occasion I had them do an install for me, and I forgot one of the parts. They loaned me their truck so I could run home to get the part. These guys are very good. I don't know what happened in that other review, but that has NOT been my experience (or my friends experiences) at all. These guys know their stuff, and are up front and honest. They've even talked me out of work I wanted to do because they said it wasn't necesary. Check out all of the hot rods and such that go there. They wouldn't be in such high demand if they did what the other reviewer claimed - they would be out of busines. I found these guys many years ago, when I asked my co-workers where to go to have exhuast system work done, and everyone at work (gear-heads) recommended them. And several of these guys lived in Fairfield and Vaccaville, but made the trek to get to WC Muffler. I strongly recommend them. Go there (or call them), and talk to them. Then judge for yourself. I think you'll be another happy customer like me and the many co-workers that have had them work on their cars. __________________________ ETA 1/23/14 Had them crank my torsion bars just a tad to gain ~1" on the front of my '97 K2500 Suburban 4WD, and do a front end alignment. Excellent service, once again (as I waited). In addition, they removed my slide in trailer hitch, it was stuck really bad. I had previously beat the snot out of it, with no luck. I had to use a hammer to get it in the last inch or so when installed, and that was in 2006 Add to that several salt water boat launches, and that baby was really stuck. Even the cotter key and pin required heat and a lot of pounding. Steve used a torch to heat up the female hitch receiver, and with a lot of pounding got that bad boy out. It was a PITA! And he didn't want any money for it (I practically had to force him to take $20. Again, old classics on the racks, and in the lot. Still 5-Stars no doubt! read more

New to the area and needed some work done on an old hot rod of mine. Lucked out by taking a guess with these guys. It's a car I get nervous leaving in the hands of someone I don't know, but the minute I showed up and met Steve I knew I was in good hands. He'll be my go to for all the family cars for now on!!! It's rare you come across someone trustworthy, honest, and straight forward in this line of work. These guys have it nailed! 5 stars read more

So I went to get a muffler delete for my e92 328i. Called them over the telephone, a woman answered nicely and gave me a reasonable quote. When I came over, I met this guy name steve. To begin with, he's rude and doesnt care about what you want. I ask for a decent, not too expensive exhaust tip and the guy called me a moron for asking such stupid question (I don't really care, some person are just rude to begin with). When I asked him for a lower price, he told me "This is not a bargain store, its a custom shop" then gave me my car key and walked away. Well, imo type of owner is surely bad for business. And being a jerk with an attitude you just lost yourself couple hundreds. Guess who's the moron now. read more

Great muffler shop! I called around to shops all around the bay and just kind of stumbled across West Coast Mufflers. I called on a Wednesday morning to see when I could get in to do a Flowmaster muffler and stainless dual exhaust with black tips on my F-150. They said they could get me in that afternoon at 2. When I showed up, they were very helpful in talking with me to make sure I got what I wanted, showed me the tips and asked me where I wanted them placed on the truck. By 4:30 the truck was done. It sounds amazing, and looks even better! All the welds look to be very well done. Thanks guys! read more

Linda and Steve are amazing here . Service was 10 out of 10 . Linda is the person at the front desk and she made all the paperwork and answer all the questions that I had for my exhaust as smooth as possible. Steve is very knowledgeable and the welds are nicely done . I'm not sure entirely what this shop is capable of doing but from what I can see is they do just about everything on the hot rods in LS engine and trans and I'm sure they do way more. Definitely bringing my car here for future work and I would recommend this shop to anyone . read more

I have now taken two of my trucks here to put flow masters on. My first was a 2014 Silverado. They did a great job and sounded amazing! Last night I traded my 14 model for a 16 model. And first thing this morning I'm back putting flow masters in this new truck. The staff here are really great and knowledgable! They take time to explain everything in details and options. Today they were also so kind to do my truck on the spot with their busy schedule. Great place and would highly recommend to everyone! read more
