Not cheap, but John knows what he's doing, whether modern import or domestic, or for us with ancient barouches, anything from the first half of the last century. You'll be in good hands with this 75-year-old shop, operated by the man who's been there the past 40 years, since a lad, learning from the old timers, much craft and knowledge hard to find well into the 21st century. Whatever your car Auburn, BMW, Borgward, Buick to 240-Z or Zephyr, John knows it, and goes the extra mile. A solid 10, two thumbs up, which is about all i've left in my pocket, but again, this is The Shop you want. read more

John & Dave do great work. Brought in my car with short notice after the exhaust system fell off. Due to the limited aftermarket options & lack of OEM availability I was worried this might be the issue that sends the car to the grave. John was super helpful & accommodating. Told me to bring the car in & within moments of the car being offloaded from the tow truck he had it on the lift. The car was there for about 2 days & I had back by Friday that week. Great service. I'll be returning to broadway muffler service for any future event with my vehicles. read more

Quality work, attention to detail, and great communication. I will go back for my other vehicles in the future. read more

This business comes through again! I recently purchased a 67 Mustang coupe and unfortunately one of the exhaust pipes was damaged while car was being loaded to the transport truck. As soon as I received the car, I brought it to Broadway Muffler and John had me back on the road same day. He also made recommendations to improve the exhaust system clearance to prevent future damage. read more

John welded a crack in my exhaust manifold. Charged me half of what he estimated up front, and did great work since the car passed smog afterwards. Saved me thousands I would have otherwise spent replacing the part. Honest and stand-up guy and does great work. read more

Great service the guy knows what he's talking about. Fair price better than any place around very picky up. How is Mufflers look and how his tail pipe tips look read more

John was great--thorough and fast. Super appreciative of his honesty and fast work. Fixed my issue in a couple of hours. If I attempted going to my dealer for this issue 1) it would've taken at least a week to get it fixed 2) dealer probably doesn't do this kind of repair and would've upsold me to a whole exhaust system 3) would have been way more expensive. So thank you to John and Broadway Muffler for great work at a great price. read more

I brought my car in to have an aftermarket muffler installed and had a great experience. John was very communicative, efficient, and accommodating in terms of letting me drop off the new muffler a couple days prior to its installation. Everything looked great when it was done. I also thought the cost was great and very reasonable. I would definitely take my car back to Broadway muffler for future service. read more

Went to have a new muffler installed a flowmaster 10 series , when I picked up the truck after the install I looked up underneath to find out it was not a flowmaster , John the owner tried to convince me that it was until I went underneath again and took a picture where it clearly says street flow on the muffler! , I don't appreciate being lied to! he charged $113 just for the muffler which is more than what a flowmaster 10 series retails for, I would not trust this place ever again and I'm going to have another shop replace this muffler as it is not what was agreed on. read more

I needed to get a set of exhaust tips welded onto some motorcycle header pipes. John made a couple of suggestions which worked out perfectly for my needs. It was done quickly, but not sloppy. Professional service, great pricing, and overall great work. My project was relatively simple for his skill, but I would have no problem bringing him bigger and more complex projects in the future. Highly recommended! read more

Very professional and friendly. It was a pleasure working with John, I highly recommend the shop.

He put a nice muffler on and it sounds great. Thank you, John! read more

John is excellent to work with. Very reasonable and honest. I've taken a couple of my cars there and he's done a great job each time.

Best exhaust shop around, couldn't be happier with the amazing work from John at Broadway Muffler! John installed my Chris Alston's Chassis works subframe connectors and G support system and driveshaft safety loop! John then tucked my 2 1/2 inch exhaust up in that subframe system, all custom for me! If you want someone to take there time, do it right and charge a very reasonable price, look no further! Thanks John, you know Iam bringing my next ride to you!!! read more

John was super nice and provided great service to secure the replacement CAT on my Sequoia. Highly recommend him.

John replaced both my catalytic converters on my Yukon the other day and he was able to handle it for me a couple days after I called him, truck was done in a few hours, very happy with his work and appreciate that he got it done quickly & for a good price for me. read more

John was recommended to us by Justin's Auto and the goodness. We had a rattle for a few years and our dealer could not figure it out? John knew what was wrong in about 2 minutes and once the parts were in, had it fixed on an hour! read more

My experience was beyond five starts! My catalytic converter was sawed off of my car and my mechanic, Paul (of Frank and Paul's Auto Repair) immediately directed me to John and his services. John was incredibly patient, reliable, and kind throughout the entire process. This is especially important to note as my insurance created quite the confusion and lead to my car not being worked on for three full days. John was ready the moment I drove in and very prompt to accrue the necessary parts. I am very thankful to have had this experience with John and highly recommended his services! Honda would have cost me triple and certainly would not have treated me so well. read more

The reviews for this business are spot on! I needed a new exhaust system for my Datsun 280zx Turbo project car and needed someone who is both an expert and cares about their craftsmanship. From the very beginning John was there to help and listen to what I wanted done. When we came across an issue he was patient with me and thoroughly explained our options. In the end, he designed a special joint that was able to connect the exhaust system to the turbo's strangely shaped down pipe. John is very fair in his pricing and does quality work. When I dropped off my car I was expecting a very nice system, but ended up with a great looking and sounding exhaust system that wildly exceed my expectations. Overall, I can confidently recommend John for any type of exhaust work. He's a great guy to work with, and seems like the type of person one can hangout with over a couple beers. read more

My catalytic converter was stolen from my van early Saturday morning in Walnut Creek. One of my neighbors heard the noise and called the Walnut Creek police - they came immediately and were able to catch the guys and within an hour returned the catalytic converter to me. Great police work - Thank you Walnut Creek Police! I spoke with John at Broadway Muffler early Monday and by Tuesday afternoon he had re-welded in my catalytic converter. Great work, really professional and gets the job done fast. I highly recommend John and Broadway Muffler Service. read more

Thank you John for the awesome welding work on my truck. This is a go to place! Very much appreciated.

Having head aches while driving - Check! Weird Smell of gas and exhaust in the car while sitting in traffic - Check! My car sounds like its popping pop corn - Check! I have and exhaust leak People! My boss and I were sitting in traffic one day and she says, "Ivy haven't you been complaining of having head aches every day?" Yeah, I have been. "Well, your car is leaking exhaust into the passenger compartment. You need to go get this car fixed." I took it as a good sign because I can say now that I have been just so busy at work that I haven't been able to go get the muffler fixed on my company car. Bad sign that its making me sick. I have a rule about place's I take my vehicles to get fixed, whether my personal vehicle or my company vehicle. The shop has got to be clean. Some people may say what does that mean its a dirty repair shop. NOOOOO! They must have a very clean work area to meet my standards. This place does. I wanted to take pictures but I didn't want them to think I was weird. John the owner, went out of his way to make sure my car was done that same day because there was a weird part that they may not have been able to get. He hustled and got it for me because I only have this one car to drive and wouldn't have anything or anyway to even get the car on Monday. Great customer service, fast and efficient. I didn't care about the price because I needed to get the muffler fixed no matter what. read more

Finding a good honest auto repair shop in Contra Costa can sometimes be frustrating. I'll tell you from my experience, if you have anything going on with your car take it to Broadway Mufflers in Walnut Creek FIRST. Here's what happened... I had an unknown random, persistent rattling noise coming from underneath my Chevy Tahoe. It was very frustrating and somewhat embarrassing... I had taken my car previously it to two other shops in Pleasant Hill and Concord who had failed miserably at pinning down where the problematic noise was coming from and how to fix it. John at Broadway mufflers was recommended to me. When I called him on the phone and explained what was going on he immediately had a good guess at exactly what the problem was. Due to his confidence I schedule the time and brought my Chevy Tahoe down to him. He took a quick listen, and told me he thought he knew exactly where the problem was. Right then and there he had my Tahoe up on the racks and he fixed the problem in less than 20 minutes while I stood there and watched. What I'd really appreciate it about Jon is that he actually showed me exactly what the problem was. He took me under the rack and SHOWED ME what was going on. He fixed it quickly and I felt like I was chopping up conversation with a good buddy. When I asked him how much I owed him for the fix, I was floored at how fair his price was. The guys down at Broadway Muffler are honest and very transparent. I asked him if all he did was Muffler's since that is obviously the name of his shop... He told me that he basically specializes in anything underneath the car. Mufflers, catalytic converters, custom exhaust systems, brakes, welding and obviously he's proficient at pinpointing persistent unknown random rattling noises that other shops were baffled by... If you have anything wrong with your car I strongly recommend taking it down to Broadway Mufflers in Walnut Creek first before you go anywhere else. read more

My car started making a ticking noise when accelerating and I had an idea of what it was so I brought it to John to have a professional diagnosis it. John took a look and told me what he thought may be wrong for free and gave me recommendations on what we could do next to fix it. I am a young woman and it can be intimidating going to auto shops by myself. John was always respectful and honest with me which made me feel secure in his work. He gave me an estimate of how much it would be to fix and even told me if I found parts online he would use and install them for me. John worked on my car for 8+ hours and discovered the issue was not what we originally thought and that he wouldn't be able to fix it. He didnt charge me a dime for all the services he provided and recommended places that do the kind of engine work required to fix the car. I really appreciate his honesty and will be recommending local family and friends to go to him first for car trouble. read more

Did an amazing job on my 1974 c10 ,took the time to tuck everything nicely will definitely be back with my other cars thanks John.

This is a one-of-a-kind place. I have John do all my exhaust and muffler work and what I appreciate more than anything is he knows exactly what I like. I recently dropped off my 2017 Silverado and he spiced up the truck for me! It sounds great. People this place is first class with that old school customer service feel. If you pick the best you get the best every time! John and team at Broadway Muffler thank you again for a stellar job at a decent price I appreciate all you do!! read more

John was honest and saved me from an unnecessary repair. The smog check guy told me I needed to replace the catalytic converter because it was from out of state. John had a look and told me the catalytic converter was just fine. I took my car back to the smog check guy and asked him to look at the catalytic converter again. I passed right away. read more

John is perhaps the most honest guy I've met in this line of work. He just did awesome job on my 62 bonneville, he's done the exhaust on my Camaro and a couple other vehicles over the years. One car I thought needed a muffler, I was prepared to pay for a muffler, and it was just a loose hanger. No charge. Highly recommend John. read more

This is a business you can trust. I dropped by to have them look at my rattling muffler, and John, the owner, put it up on the lift and tightened one bolt, fixing the problem. He charged me NOTHING! I even tried to pay. I guess since it only took 30seconds he just let me go for free. GIve this man your business, he's one of the few honest mechanics out there! read more
