Great job on installing a catalytic converter on my old truck. Will return for more work when necessary.

I couldn't be happier with the resonator installation Gary did on my car! His expertise and attention to detail were top-notch, and the results speak for themselves--my car sounds much better as I was looking to eliminate the drone from the Borla muffler. Gary was professional, punctual, and took the time to explain the process, ensuring I felt confident every step of the way. His passion for his craft is evident, and he went above and beyond to make sure everything was perfect. If you're looking for someone who delivers exceptional quality and service, Gary is your guy. Highly recommend! read more

I wanna start off by saying Gary is a great guy! Super easy to talk to, patient, very friendly and polite. He is also very flexible and is willing to work around your schedule. He installed a midpipe and muffler on my 2025 Lexus IS 350. It was a custom system, not your typical bolt on full catback exhaust system, even with some hurdles that he encountered during the installation he pushed right through them showing off his expertise, determination and problem solving skills. I would recommend him to anyone looking to do any sort of exhaust work! read more

Gary is hands down the best when it comes to exhaust work. Super friendly, honest, and genuinely cares about getting the job done right.

Ask for Gary! He's the man, Quick easy and at a reasonable price! I was happy with my service, would definitely recommend!

I came to Performance Muffler with a quote from the dealer for a $2200 muffler replacement. Gary saw me the same afternoon I called. He isolated the issue quickly and within an hour had a fix. It involved cutting and welding, and in the end he charged a very fair $300 for the repair. Gary is honest, trustworthy, and a great technician. I would highly recommend anyone who needs muffler or exhaust issues to come here. While I was waiting, I was talking to a return customer that drove 40 miles to see Gary, since he was the person he could trust. read more

This is the best muffler shop I have ever been to! I came in based on the recommendation from Discount Tire, where I just had a tune-up and a catalytic converter replacement after it got stolen. I was looking for a muffler shop to make a custom shield for me, and Gary was fast, reasonable, and friendly. He offered me a cup of Armenian coffee during my consultation, and he was very thorough in the actual service. The shield was perfectly done, and he also replaced my alternator, which was nearing the end of its life, shortly afterwards. He even replaced the battery in my key fob for me as a courtesy. I highly recommend Performance Muffler. Gary is the real deal and is professional, kind, and caring. He does a standout job with everything and goes above and beyond for his customers. 10/10! read more

Excellent customer service, reasonable price and very friendly. After two catalytic converter thefts, Gary understood my concerns regarding my catalytic converter theft protection shield and the issue I was having in getting a smog certification for my Honda Element. He removed the old shield from the catalytic converter which did not have a window and I was able to immediately get a smog certification from Allstar Smog Repair directly across from Performance Muffler. After the smog check was completed, Gary expertly installed a new anti-theft protection shield onto the catalytic converter underneath my Honda Element, which now has a window so I won't need to have the shield removed each year when I need to get a smog certification for my Element. I thought I would have to leave my car overnight with Gary, but he was able to complete the task within four hours. I highly recommend Gary! read more

Had my catalytic converter installed here and needed some additional custom fitting for my headers and exhaust. The owner (Garo) is a super nice guy and very patient knowing I'm a bit OCD. He took the time to align and install everything perfectly and made sure I was happy with the work. I'll definitely return there if I have other applications to do. read more

If you need any work done bring your car here to Gary. I needed 2 extra resonators added to my aftermarket exhaust that already has 2 resonators. I have a 18' q60 btw.. I called a few places some gave me a ridiculous price other places told me I needed to bring the car in and one didn't have time till next week. I called the shop after hours and he returned my call within a minute he had a spot the next day. I told him my situation he understood exactly what I wanted done (no doubt from years of experience) I came in on Saturday we both talked about a couple different spots and I asked his opinion and he listened to what I wanted done also. Very genuine, humble and caring person. His work speaks for itself and prices are very reasonable! Don't waste your time take your car to Gary you won't regret it. read more

I called Darry and told him I had a modified Honda Fit that I would like to make quieter. I had purchased the car as is a few years ago and I wanted to see if anything could be done to make the loud noise quieter. I didn't think much could be done but Darry said he could put on a quieter muffler. I left my car and I came back to a normal sounding car! I'm so pleased and grateful something could be done and it was exactly in my budget. Darry was really helpful and knowledgeable and was able to take a loud car and make it sound normal!!! So happy I called and followed through, it was way worth it! read more

I came here after reading the great reviews, as my car was acting up and had a strong exhaust smell. After explaining my car issues to a friend who knows about cars, he suggested someone who specialized in mufflers. Shame on me for having too much trust in someone based simply on their great Yelp reviews. I paid master mechanic prices to get services not promised. There was a heavy exhaust fumes coming from my car and when I dropped the car off it was one of the aspects I told him about. He called me a few hours later telling me I had a cracked manifold and quoted me a price, assuring me that my car should be in great shape after that. Though I felt the price seemed high, I agreed despite also my second red flag asking if I could pay in cash. Hmmm... ok I thought well if this fixes my car great. I picked up the car as it sounded a lot better than when I dropped it off, thus I was like great it's back in business. Only for it to stall on me down the street as I was getting gas. No big deal I thought, after all it was on empty and perhaps that's all it needed. Nope, check engine comes back on and then the car starts to jerk. I took it in the next day and he drives it around for a bit, pops the hood and finds that one of the hoses are broken. He replaces it at no extra cost and then says we should be good to go. Drove it off again and well again have issues and check engine light comes on. Then the exhaust smell is back. I take it in the next day, he explains that these issues that are coming up aren't his field of expertise and that should be done by someone else. Wait so I pay $750 (which I was told later I overpaid) for something that didn't even fix the reason I brought it in. Buyer beware. I always feel a man's reputation speaks highly of him, however disappointed that trust was taken advantage of by being overcharged and then told the problem was out of his specialty. He should have been upfront about that aspect in the beginning. read more

Quality work here. Gary (the owner) gave me a good price on installing a catback exhaust on my 370z. He even removed some stripped bolts (that I had created on my own attempt to install an exhaust). He installed it quickly and even waited for me to arrive to go over the work he had done in detail. If you need exhaust work done, this is the place. read more

Had an issue with my exhaust, didn't know what it may have been. So I decided to take it to Gary and his shop, first impression was great, he stopped what he was doing to assist me, lifted my car and told me exactly what was going on with my noisy exhaust. After a week or so I finally received my exhaust from UPS and went straight to Gary so he can install it!! It literally took him 20 minutes to do the job the the results were phenomenal, not only didn't it look great, it sounded amazing as well, I recommend this place to all my friends da and family!!! Thanks again Gary!! read more

To me, getting work done on my car is like going to the dentist! You never know how bad the problem is until its been inspected and then you wait to hear how much its going to cost! I was having problems with an oil leak coming from my muffler, so I took it in to Performance Muffler to have it inspected. Gary helped me as soon as I drove up. He was very friendly and knowledgeable and put my car up on the jack to take a thorough look. He reassured me that the leak was not a big problem and he could take care of it within a couple hours. I felt relieved and asked him to go ahead with the work. I was extremely content with the price he quoted me, and glad that honest people still exist. If you want quality work with reasonable prices, you can't beat Gary's service! read more
