If you care about quality work this shop is for you. Outstanding craftsmanship and reasonable prices. John the owner is a pleasure to do business with. Hes enjoyable to talk to and is immensely knowledgeable. I highly recommend Broadway Muffler!

The best exhaust work Ive ever had done and for a fair price.

I mean they fixed my car so they did their job. Location is not prime as its very difficult to get out of parking lot on a busy main street. Dude working there was very nice, though Id prefer going somewhere that doesnt hang their political preferences up in the workplace for everyone to see. Glad they installed a metal plate so my catalytic converter doesnt get stolen again.

John completely redid the exhaust on my old truck. All the welds look great, the exhaust is supported correctly, and the work was delivered promptly.He took time to talk to me about what I wanted and was professional throughout all interactions.

Best muffler shop around. Great custom work!

John is awesome. We talked about growing up in Walnut Creek. Hes a very genuine person. He fixed my class c RV in an hour or two. Great price and great service. Would highly recommend.

Took my Mazda hear a couple years back but never got around to making a review. I had custom made bolt on exhaust I bought online and just needed it installed. He checked the exhaust and made sure it didnt break any laws and quoted me a decent price. I didnt technically have an appointment because he wanted to make sure he could do the job first. He still got the job done within a few hours. Great price and quick work. Customer service was okay but he seemed to be in a rush, so he just trying to get stuff done ASAP. He had a lot of cars and was running the shop by himself when I went there, so I understand. Would go back again if I ever need anything done for sure.

Being a car guy I have been looking for a new go to for my custom and tweak work that not so many places do anymore. Fast friendly and knowledgeable!

Extremely unsatisfied with their job.We took the car and left it with John (the owner probably ) three months ago. We have installed it halfway but the muffler was kind of longer by an inch for my car so we asked him to cut the pipe and weld the muffler to the mid-pipe. He called us latter saying there is nothing wrong with the exhaust and he needs to redo everything and it will fit. in two days the car was ready, but he just welded the mid-pipe to where it connects to the muffler and charged us $300. The car looks horrible the exhaust is sticking out so much and $300 is completely unfair for just a cut and weld. (there are tons of YouTubers out there paying $70 for this kind of job. So, its your choice to take your car there or not, but I would not recommend it! (I can upload pics based on the request)

John is a really down to earth guy who sticks to his word. Doesnt overcharge! Great quality work for a good price. Will be coming back.

Easily one of the best automotive service providers in the area. I started taking my vehicles there in 1980. Same honest, reliable and reasonable guys there the whole time. You wont be disappointed.

Finding a good honest auto repair shop in Contra Costa can sometimes be frustrating.Ill tell you from my experience, if you have anything going on with your car take it to Broadway Mufflers in Walnut Creek FIRST.Heres 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 Id 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 Mufflers 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 hes 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.

These guys are great.

Ive come here for two mufflers. Magnaflows, both times by owners suggestion. Sounded amazing. Too bad theyre closed today, because I want them to do the exhaust on my new car. They do work very hard though all week ( father + son? Im not sure.. )Very nice, fast, honest.That is all.

Great shop. Ive had a few services done here and the owner has always been honest.- Previa 2nd cat replaced (x2)- 50 state legal catalytic converter in my Infiniti M30Again, we talk about honest, let me tell you. I thought I had gotten an exhaust leak. I was expecting a down pipe work or exhaust work as I was having a loud sound. I popped my hood and he immediately saw that my EGR pipe came undone. He pointed it out to me and that was that.Good service and better the more you become a customer with this shop.Prices are fair and maybe better.Very honest and trustworthy!

I needed a new catalytic converter for my 25 year old car. John gave me an instant quote and stuck to it when it turned out that I needed a more expensive replacement part. He was done when he said he would. What more can you ask for?

Very knowledgeable installer. Pleasure doing business with you. Thanks!

Amazing owner and install :) Fast, Affordable Professional.

Ive never been treaded so well, fair and honestly as I was at Broadway Muffler, they could have just fixed what I needed but instead told that before I made the investment I needed to find out why the oil was leaking. Such honesty deserves to be rewarded, that is why I give them more than a 5 star rating!

Racist and quoted me $400 for a simple muffler delete. Don’t waste your time and money.

Great staff. Honest and friendly.

The most honest shop around

Very good and honest mechanic.

Called and hung up on me. No customer service at all. Don’t recommend this place.
