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

This was a great find! I had to replace the catalytic converter on my 2006 Acura TSX and Gary was able to do this without an appointment at a very reasonable price.

Gary is AWESOME!! If you need a muffler or exhaust work on your vehicle, GO SEE GARY at Performance Muffler, he will not disappoint! He installed a new, heavy duty muffler on my pick up truck. He fixed the mounts/hangers that were no longer attached. He reshaped the mouth of the tailpipe (it was a little bent out-of-shape). He bent the exhaust pipe back into the correct shape. He re-positioned the tailpipe back into the correct position. The previous owner of my truck had apparently backed into a high curb or some object and that caused all the damage. But Gary fixed everything! And he was fast, friendly, professional and did it for a good, fair price! I stood by and watched everything everything he did. He is a Master of his craft, obviously, after watching everything he did. Totally happy with his work. This is probably the best muffler shop in the North Hollywood / Los Angeles area. read more

I had recently bought a car that wasn't passing emissions due to a clogged catalytic converter. I purchased a cat from autozone and brought it over to get it installed. As I arrived, a kind gentleman greeted me and observed the cat I had bought from autozone. Before even lifting my car on the jacks, he realized the cat I had brought over was in fact the wrong one for the car. Luckily he had the one I needed in stock for cheaper than the ones parts stores had. He replaced the cat and did a great job. Very clean and organized shop. Will recommend to anyone. read more

Gary was quick to get me in and out when I came to him to replace my stock muffler with my new Flowmaster. I really loved the fact that I called him in the morning and within the hour he was able to work on my car. When I got to his shop the experience was very straight forward and professional. He provided really good customer service and asked me if I had any questions and explained to me the benefits of the service he was providing. After the explaination, he got right to work making sure everything was fit and held into place after he finished welding. I was able to purchase an exhaust tip from him that better suited my car and even though I didn't have the extra cash for the tip he still put it on and let me pay him later in the day. This was a true testimony to the honesty and integrity in which Gary conducts his business. I would definitely recommend him for any and all exhaust system needs. read more

Gary is a great guy took care of me and my girlfriend. He is really fast and has great quality welds no ugly cheap looking welds that dont hold up.

Performance Muffler - Auto Repair Near Me - North Hollywood, California

My experience wasn't the greatest one. I had to come back several times to fix the alignment of my mufflers (one was sitting lower then the other one). I originally went there because they are highly rated. Being a car guy I know a lot about exhaust systems. I am happy now (they almost got a 1 star), only because one side settled at the same height after time (writing this review 1 year later). Gary is the cheapest option for exhaust mods in SFV and he does a great job. He didn't try charging me extra for his mistake (see King mufflers review). read more

This was exactly the shop I needed when I had two broken exhaust hangers on my land cruiser. I had other shops tell me the exhaust system needed to be replaced but I knew it could be fixed if I found the right person. Sure enough Performance did an awesome job and it's holding up nicely two months later. read more

I don't usually right reviews but I had to right a review so everyone could find out about this business. Being a female I am always nervous to take my car in for any type of repair or service but with Performance Muffler I had no reason to be nervous. They didn't try to upsell me or sell me any unneeded services. Gary greeted me offered me coffee and gave me his honest advise about the services my car needed. This is a very clean shop, with no hidden fees or upselling. They are very friendly and offer quick service. I will definitely be returning and telling all my friends to go see Gary at Performance Muffler for their automotive services. read more

Okay so this is my second review I think. I really don't take the time to do this but I had to leave a review for Gary and Performance Mufflers. First off, I ordered Headers for my 2015 Subaru BRZ and was very skeptical about where to get them installed because it's a high performance sports car. I found Gary's shop online and took a chance. I went to his place and he was so nice and very professional. He let me assist him in the installation of my header because I wanted to learn how to work on my car so I became his assistant and he was so nice in explaining what goes where and why this part belongs here and such. Anyway I'm not sure if this post is making any sense but I would recommend anyone that has muffler needs to go to him! He is so polite and kind and very knowledgable - once starting my car it sounded very bad and he assessed the situation and found there was a slight air leak and fixed it in seconds. My car sounds so good and is so deep and throaty and sounds better than a Ferrari 430, compliments of my amazing boxer engine! Price was very fair and half of what a tuning shop wanted to install my headers. Very blessed to have met Gary and very happy I Took a chance with Gary. Riley pulls so much harder now and feels amazing! read more
