Had Steve work on my Mustang had him and cut some exhaust pipes that clamp on to my cat converter and he did an excellent job for the price that he charged and had it done In less than a day! read more

One of the best mechanics I've had the pleasure of working with in a long time. A no BS type of place, which I love. Steven had to order a part for my Volkswagon Golf. Upfront about the cost, no surprises (and a very reasonable price). Once the part came in, he had me in and out in a day. Highly recommended. read more

Steven was super helpful! I was frustrated with a catalytic converter issue that he was able to fix without any issues. He was very patient helpful and friendly. I would recommend this place $100 percent! read more

I had a catalytic converter issue and brought it to Livermore Muffler. As with other service I had done here, it was done quickly, efficiently, and at what I consider a very reasonable price. This is my third time here for various vehicles over the past few years and I've had the same great experience each time. I definitely recommend Livermore Muffler! read more

I had an awesome experience with Steven at Livermore Muffler! He was super friendly, honest, and took the time to explain everything clearly.

Was recommended to Steven by Nick Germanno from OutKast customs. Had ridetek coil over suspension installed. Existing 3 in pipe from muffler to tailpipe could not be used anymore due to clearance issues. Recommend to go with 2 1/2 in exhaust pipe. Installation, quality of work was superior! Also repaired some existing exhaust leaks! Was clear, straight forward with pricing! Will definitely return for future exhaust work and will recommend to others about the excellent service Steven did on my car at Livermore Muffler Shop! read more

Steven was recommended to me by Shaffer's Off-road and I had a great experience. He helped me out with new cats and a custom exhaust on my Raptor. My only asks were to make it loud when I'm on the throttle and, more importantly, make it so it'll survive regular desert off-roading - and Steven killed it! He's a super nice guy, has a cool shop with bada** cars, and does quality work. What more could you ask for? read more

Honorable service is the best way to describe this business. Took him a wierd welding problem. He said he'd give it his best shot. he tried and it didn't come out the way HE wanted, so no charge. I was hoping for a different outcome too, but my problem is solved and that's why I give him 4 stars. Minus one because we didn't communicate well but that's on me also. read more

Great service, quick.and reasonable cost. Had to replace my catalytic converter on my motorhome. Had some great deterrents to future theft, read more

I am a bus driver for a Livermore company. The bus needed a new muffler and the mechanic recommended Livermore Muffler. Stephen replaced the muffler in a timely manner, and his fee was more than reasonable. A few months later the safety strap came off the muffler. Once again Stephen fixed the strap on the muffler at no fee. This man is an incredible example of a great business owner. He does all his own work and stands behind everything he does. Please go visit and support our local business. read more

Got some mid pipes installed on my Mazda 3 Hatchback. Steven is a stand up, no bs guy. Get your exhaust work done here if you can! read more

My car has now 300,000+ miles. It is still running like a champ. Thanks for a job well done on my transmission. Toyota Echo 2001.

Great service and quality. Steven is a standup guy and appreciate the direct info he provides.

Just straight forward honest service, good value, time efficient and easy drop off/pick up. If you need exhaust work, especially muffler delete, I'd go here. read more

I feel compelled to write this review today. I have used Livermore muffler and Steven on a few cars in the past today I called him in a bind after my wife, hit the muffler and exhaust on our truck. I called Steven asking him if he can squeeze us in and he said bring the car by and he'll try to figure something out. He is such a nice guy. I can't even have words to describe. He literally took the car and fixed it for us really quickly, allowing us to get back on the road without a hiccup. If you're thinking about getting any work done to your car I definitely recommend him and his shop. He's a standup guy and nothing short of awesome thank you, Steven. read more

Amazing customer service and was really pleasant to work with. The welding was done thoroughly and it looked perfect.

This was my first time using the Livermore Muffler Shop and I'm going to throw them 5 stars all the way! A long story short, I recently bought a very nice 2015 Chevy Silverado truck with a 5.3 liter Vortec V8 engine. It sounded like a quiet sewing machine and not like a truck should sound. (IMO) After reading all his Yelp reviews I knew this was the place to go here in Livermore since they are highly rated. I stopped by their shop yesterday morning and told the owner, Steven that I wanted my truck to sound like a V8 should sound and he installed a Flowmaster 40 series muffler that same day at a very good price. I mentioned that I didn't want to go to loud and he said "if the Flowmaster 40 is to loud, he would warranty his work and install a quieter muffler if I desire and comp his labor". After driving my truck overnight it was a bit to loud so I decided the Flowmaster Delta Flow 50 series would probably be better for me after watching Summit Racing Youtube muffler comparisons video and stopped by to see Steven this morning. I'll be damned, he is going charge me the difference in muffler costs since the 50 series is more and comp the labor like he said..... It doesn't get any better than that, Steven does super clean work, has a great pricing structure and is a man of his word! If you are in need of anything muffler/exhaust system related, go to Livermore Muffler Shop, you won't be disappointed! read more

Yes. Great work! Fair price ! I hadn't any idea what I was getting into but my 2004 Chevy Tahoe runs like it was new. Thanks again!!!

After reading all of the scary incidents of stolen catalytic converters on Nextdoor. I called my mechanic and he gave me a quote of $165 if I also purchase the Cat Shield from them or $225 if I purchased it myself. I went shopping around...talked to Dublin Muffler and their quote was also high. I then called my favorite body shop....California Reflections and Kevin said they don't, but he referred me to Steven at Livermore Muffler.... I did a quick check on Yelp... and he has 5 stars. No one has five stars.....maybe 4.5 stars, but he has five stars. He said he would put it on if I bought it. Maybe $150 or less depending on what it looked like.... so I ended up buying it from Ebay for $100. It took a couple of days to get here.... and when I bought it in..... he put it on for much less than $150. Along the way... he told me about how he got into the busy of putting cat shield and bar protectors over the catalytic converters. Someone stole his from his Toyota Sequoia.... so he got two for one... since my other car was a Sequoia ... he was able to do it for $250. read more

I've been working on cars and trucks for over 30 years, and in that time, I've worked with countless automotive shops all over the country. And while most are good, few are exceptional - Livermore Muffler falls into the latter category. I had an issue with the exhaust on my 20 year old Jeep Grand Cherokee (something I wasn't equipped to handle at home), and after seeing Steve (the owner's) Instagram page and reading the reviews here on Yelp, I decided to drive the 35-miles to visit his shop. First thing - Steve (the owner) is a die-hard car guy who, while not old, treats his customers in an old school manner with courtesy and respect (something seldom seen these days). He then took in my Jeep, diagnosed the issue quickly (bad baffle in the old muffler and a broken bracket), and then fixed it in no time making my old Jeep sound like new again with the quality of his work being fantastic! Was it worth the 45-minute ride to get this kind of service - absolutely! And better still, I now have a new exhaust shop who will be getting all my business - a good thing too, because I have a bunch of old cars! read more

Steve is a great guy and knows his cars. Replaced some bolts and a gasket that flew off my car car while driving. I did have to wait a while before my car got looked at because he was so busy. Come ready to drop off your car or have an appointment! read more

Livermore Muffler Shop - Bolt went flying off the car while driving. Steve fixed it right up. - Auto Repair Near Me - Livermore, California

Steve does excellent work. Keep in mind that he's a one man shop! His pricing is very competitive and his work is high quality. He is very communicative and flexible with drop off/pick up schedule. He worked on my jdm van and put an entire free flow exhaust system and it is now ready for some Initial-D action. Thanks Steve!! read more

My 2010 Prius had its catalytic converter stolen. The Livermore Muffler Shop was able to find its non-OEM California approved replacement and installed it in very good time. My car just passed its smog test with this replacement with no problem. Steven was very knowlegeable about the its and outs of Prius catalytic converter replacement. Very happy with the great service from this shop. Highly recommend! read more

Major RAVE to Steven! Our softball team, Lady Venom, has a pitching machine that needed a bigger attachment and needed welding. We took it to Steven, and he fixed it for us immediately. read more

Steven is all around a great guy and come highly recommended!!! I came across this location after reading many recommendations on nextdoor. My catalytic converter was stolen from my 2007 Prius on a Thursday night. Called him and dropped off my car on a Friday. I told him if he can give me a competitive price (compared with 2 others) he will have my business. My ordeal couldn't be claimed through insurance. He had my car completed and ready for pick up on Tuesday! Super fast service and understanding! He even installed a deterrent for any future thieves read more

Super cool guy that owns and runs the shop! Very professional and customer service oriented! No funny business here!! My car failed smog cert. and the place I originally went to charged me 75$ and said they would look at what needed to be fixed for another 200$ and then mentioned they could also fix it and it would probably cost 1,200$ for the part and labor. So I went home and called around and got ahold of Stephen. He said he could look at it real quick no charge. So I stopped by and he told me what needed to be fixed, he ordered the part and gave me a much better quote than the original spot. He said hey come by Wednesday morning and we will have it done by the end of the day. Wednesday comes around and when I came to pick my car up (super speedy, just a few hours after I dropped it off) he told me he replaced some exhaust pipes as well because they were all bent up (little Nissan Altima off-roading) also no charge! Definitely coming back!! Thank you Stephen! read more

Steve does great work and his prices are reasonable. That's hard to find these days. As long as I live in the area I'll be using Steve for all my emissions related needs. read more

Great work done by Steven! I've had him do many of my cars as well as my street/race car which gets driven hard and I have to replace my mufflers frequently. I wish the mufflers lasted longer than his work. Great work and a great guy! read more

Took my Mercedes in for some exhaust adjustment. Steve (the owner) greeted me, and had my car completed in about two hours. His work was excellent, and reasonably priced. Highly recommended for all things "exhaust"! read more

Steven did a GREAT job on my custom exhaust system.

I have a '68 Camaro Yenko Clone that I had a terrible experience at another muffler shop. I asked around at the Cars and Coffee in Tracy who they recommended for a good custom muffler shop. One person told me there is only one person to take my car to, Steve Porter at Livermore Muffler. He even dragged me over to meet Steve and then had me crawl under his 55 Chevy to look at the quality of Steve's work. Steve took his time and spend over a full day to do the work on my Camaro. When I picked my car up, I couldn't believe the quality of his workmanship and how much better my car sounded. For a simple muffler replacement, there are probably others who can do a competent job. For a custom exhaust system on a collector car, go to Steve at Livermore Muffler. read more

One of the best muffler shops I've been to no lie , Steve is the man he knows exactly what he's talking about and forsure takes pride in his work! Came and got a muffler delete for a GREAT price and it sounds GREAT as well . You can tell a great shop apart from one that sucks and this one is by far one of the best I been too . read more

Took our van here after it failed the smog test a few days ago. It needed a new catalytic converter welded in. Every place I called was booked until next week and some were making ridiculous quotes for $800+. I called Livermore Muffler at 9am this morning and by 11am it was done for a really reasonable price. Took the van straight to Cal State Smog (by Steve's recommendation) and not only did we get $30 off the test, it passed with flying colors!! Will definitely be coming back here for all our vehicle needs. read more
