American Muffler

I have 2004 Corolla that had check engine pointing to a cat converter. Replaced 02 sensor and reset check engine. After approx. 400miles further recheck shows cycle has not been completed. The info I gathered was that if Cat converter is bad cycle won’t be completed regardless of how many miles you put into it. Having said that, I called around for a quote and they were 325 to 500 dollars and one gave me a quote of $ 1330. Ouch! I called American Muffler and spoke with Andy, made an appointment for check/​replacement of Cat converter.
It was my workday so I had my wife brought the car in. My wife explain the problem to Andy. Andy said he is not a mechanic but he could check for check engine. He noticed that there was a pending check engine that was not reset and that he reset it. He told my wife to drive it for 100 miles and let him know what’s the outcome. Well, this morning, I hooked my diagnostic up and Bingo, my diagnostic went green meaning everything — emission-​wise — is good to go. This check engine and cycle has been going on for 5 months now. Andy could have told my wife she needs a new Cat converter for $ 400 plus but he didn’t. The honesty and integrity of this muffler shop is outstanding. Anytime me or my friends have problem with their muffler/​cat converter, I will with enthusiasm, and no hesitation recommend American Muffler.
Thanks a lot Andy. You save me hundreds of dollars and frustration.

Went down today and had them put on a flowmaster on my F-​150. Andy and Bret were great to work with and I will be going back for more work when the time comes. Came in under their quote and took roughly an hour!!! Great experience guys, thank you!

I’ve used these guys at American Muffler several times and they have always taken care of me. They have great quality and excellent prices!

I needed a muffler clamp for my exhaust tip. I figured a muffler shop would have a wide selection of sizes and the dealer charged $ 25 and takes 3 days. I stopped by and the guys were VERY friendly and helpful. He pulled the tip off for me since it was hanging limp and said if you aren’t going far just pull it off because the tips are expensive. If I ever need something in the exhaust arena, they have earned my business for sure. Less than $ 10 for the clamp. I would highly recommend.

Bret and Andy had my exhaust issue solved in 15 minutes. Great service, will be back again.

When I backed into a tall curb the body shop was trying to pressure me into getting a new muffler. Took my Miata to this shop for a second opinion. Within minutes they had my car on the rack and were working on it. Replaced the bent part and its working like a charm, all back to normal. Saved me tons of money and time. Thanks!

I own 1998 car since being an old car, every once in a while, I have something new going on:(this time I was lucky to have the catalytic converter going bad and making noise (This is related to the muffler) In any case I took the car to 2 places and they both told me that both of my catalytic converter went bad. (This car has 4 Btw) one guy gave me a price of $ 1,425 (Original part) and the other guy a price of $ 975 (After market part) I have no idea why but I did no believe anyone of these guys so I was looking around and found American Muffler. I drove there and I was talking to Andy b (The owner) and he told me that ONLY ONE is bad from what he can see (Hear) and total work will be only $ 400. he also said IF he opens and see that the other catalytic converter is bad as well. he could do both for total of $ 700. to make a long story short, after he start working (Only few minutes later) he told me that what he said in the beginning is right, only one catalytic converter needed to be replaced NOT two. with my knowledge in cars, he could say 4 are bad and I will never know. this was really good feeling to see someone so honest that not looking to screw you for your money. since as we all know, people all the time looking to take advantage of others. finding American Muffler (Andy and Bret) to be so professional and honest was a grate surprise. Andy also did the total work replacement in about 30 minutes. unbelievable!
I wish these guys would do other car repairs since for sure I would be a loyal costumer for life.
last but not least, they also gave me 5 years warranty on the work and part they did.
what else can I say? PERFECT A+++

Is the shop still open? I’ve been trying the phone number listed and it won’t connect. It’s as if they left the phone off the hook…

Brett and his team are tops! No hassle making an appointment on a Friday afternoon and when I showed up they were ready for me. Granted, I had a simple job but from what I can tell by their skill and professionalism these guys can handle any exhaust project big or small. Bonus: they are «stance car» friendly!

Just got off the phone with Andy. As for the 1^st part of this process, the man sounds legit. Based on my conversation with him I booked an appointment for next Friday. I said, «2010 Cadillac CTS — what are my options?» He was straight forward, explained my options & gave me prices — gave me confirmation that we’d get it done with the amount I bring in. I was sold when he told me I’d be able to hear what my car will sound like with the different options before anything was final — love that. I’m glad he was able to answer the phone. When a place is busy & requires an appointment that usually means they’re doing something right. I’ll confirm that next Friday hopefully with pictures… and hopefully another 5-​star review! –David

Good price and clean work! I bought a Flowmaster super 40 muffler and Flowmaster exhaust tip online, and took it to them to install on my 06 Yukon! Sounds and looks great!

Nothing bad to say about this shop. Got what I needed for a very fair price. Andy let me watch him doing the repair the entire time.

Had an awesome experience here. I wanted to do a muffler delete and Andy knew exactly how to handle it. From the time my car was on the lift to the finished product it maybe took about 30 min. The bends and welds look good and he made the exhaust look like how it should have came from the factory! It also sounds exactly how I wanted it. Not too loud and not too quiet. I definitely recommend calling him in advanced and scheduling an appointment. It’s a one man show and he gets busy but will get the work done. Thanks again, Andy!

Volkswagens are a nightmare to work on as it is, add on top of that I gave him quite the labor intensive job. He walked me through every issue he ran through so I knew his reasoning behind every modification. Guy loves conversation which is a breath of fresh air versus the cold «just me work» types in other shops.
HIGHLY RECOMMEND AM, just be ready to set up an appt since they only have one bay and they always have a lot full of cars.
5 stars for not treating me like a fool and doing quality work despite the speed bumps during install

This guy, Andy, will try to game you if you look the part. I recommended my sister to a shop I thought was legit, who went and told her they couldn’t do the cat job at their place and recommended her to these guys. I work at an auto parts company and got the RIGHT part for her and this asshole had the balls to tell her it not only wasn’t the right part for her, but that he could get her the right part, for about 500 dollars more than what she should have paid. It pisses me off opportunistic and dishonest people like this guy exist, so this is my fair warning to anyone who might not feel comfortable taking their car in to a shop because of the «shady» rep a lot of them get thanks to guys like this. Next time do the job and stop wasting people’s time.

Used to go to American Muffler many years ago, and recently needed some metal work done. Most motorcycle repair shops don’t weld. So i figured I’d check out American Muffler. I brought in a blank fender for my bike, discussed what i needed done with Andy.. A few days later everything was completed perfectly. He trimmed it with a plasma cutter, reinforced the mounting holes, added some small piping to run my electrical wiring and a mounted a plate for a brake light! The work was spot on for a fair price. (All of this was just verbal directions, no schematics, no crazy drawings –he just gets it) Thanks American Muffler

Thank you! Car sounds a hell of a lot better and tips are aligned perfectly. Price was fair and reasonable. I should have had this done a long time ago. The work was done quickly and cleanly. Keep up the good work!

Excellent experience. The work: professional. The welds: clean and proper. The service: efficient. Their knowledge: expert level. Their pricing: OMG reasonable and refreshing.
Andy and his guys really know their stuff. I took my baby, my 2007 GT500, to have resonators put it to reduce drone. Andy was fast and honest, saying it will take the drone from a 10 to a 7. I’d say it went down to a 6; it was that drastic. No upselling, not overpromising.
I asked him about my damaged exhaust tips. He actually had inventory to show me and offered to custom fit them. And the pricing was so reasonable. I made an appointment to come back a week later. Custom hangers, cut and welded tips: job done. Looks amazing too, and I’m including the welds too.
If someone had a negative experience, I can’t imagine what happened. You should understand Andy is extremely busy so be prepared to always be required to make an appointment. When working with someone that busy, I expect I need to be somewhat flexible.
I highly recommend American Muffler. Convoy St and Raytheon in Kearny Mesa.

Guys did a great job on my Jaguar XJL. They are competent, knowledge and are perfectionist.

Like all the other people say. Don’t let the look fool u. Andy is pro and knows what he is doing. I took my bmw 328i. In for a muffler delete he finish it professionally. With a sexy tip. And I had some break caliper he was nice enough to go to other shop and borrow a jack for me and tools. Super nice person and great price.
