They did exactly what I asked them to do they did a great job couldn't ask for a better job and everyone who works there is very nice. I went to Sierra Mufflers twice and both time they did a great job.

My experience with Sierra Muffler's was a good one. They show and talk with you about the problem. I do not believe that they are too expensive. They do a good job.

Went in and had a Borla Atak installed on a 21 scatpack. In and out in about an hour. Guys at this shop are super friendly and the cost is within the ball park. Highly recommend to get your exhaust/muffler installed at this shop.

Took my 370Z in to upgrade my stock muffler to AAM Short Tails. They were very helpful and got the job done quickly, and they were attentive to my needs (I wanted my tips a certain way). They adjusted the pipes to fit perfectly. I definitely plan on coming here again for future upgrades.

READ THIS BEFORE COMING HERE!!! Please do not pay attention to other reviews or the rating and make the same mistake I did. The is my second review I have ever written and my first negative review I have ever written. I've had bad experiences before but this one was so bad I am actually taking the time to write this out so it doesn't happen to anyone else. If I would give them a negative rating if I could. I took my 2011 Lexus there because it has a muffler delete and I wanted to get the stock mufflers put on. They get it up on the lift and take a look at it and say it'll be $100 to complete the job and I say okay that's fine. So I stand outside off to the side and wait for them to finish. After about a hour they finish and get the car down from the lift and say they are done. I take a look at it and I see that on the right muffler they welded the muffler piping on the outside and on the left muffler the put the piping inside the muffler tip and then welded it. So the left muffler I can see the piping sticking through the tips and on the right I can't. So I tell the guy that they are different and if they could make them the same. I didn't want the piping showing through the muffler tips. The mechanic said okay I see what you are saying, we'll get it up on the lift. Then the owner or whoever sits inside came out and talks to the mechanic and in Spanish was asking the guy what was the problem. So the mechanic explains to him what I was saying and the owner was flaunting his arms and pointing at the car and pointing at the road saying he just wants me to leave. The mechanic comes over to me and before he could start talking the owner comes over and asks me what the problem is very very very rudely and loudly. I was a bit surprised because I didn't know why he was talking to me like that since that was the first time I had talked to him but I just didn't think much more of it and I told him that they weren't even because on one side I can see the piping sticking through the tips and the other side I can't. (Still talking extremely rudely and loudly) he says nothing is wrong with the car and I just need to leave. He said don't worry I don't owe him anything just leave. I was still confused at this point because I didn't know what had happened or why he was saying that because I still thought everything was fine and I was just telling him my problem and if they could fix it. He then said "you know what the problem is, you don't want to pay I can see it in your eyes." I looked at him dumb founded because I hadn't said anything near that. The entire time I was saying that they arent even and I just wanted that fixed. I told him I never said I wouldn't pay I just want it even and fixed. He said "no they are even, you just don't want to pay that's what the problem is." So I take out a $100 bill and show him and say look. You see this. Here is your money. He then says you want it fixed and yells at the mechanic to get my car up on the lift again and says he's gonna fix it and once it's fixed I need to leave and walks inside. The mechanics that were there come over and apologize for the owner and say he's having a bad day (it was 9am) and that they would fix it. They got it up and fixed the original problem and I paid them and the mechanic apologized again and I left. It was such a horrible experience and I am a business owner myself so I can understand that it can be stressful dealing with a rude customer but I hadn't even said or talked to the guy. I would recommend any other mufflee shop but this one. I went here because it had good reviews and a good rating but it's complete bullshit. Do yourself a favor and don't come here. I hate to say it but I felt like I was being discriminated against but I didn't want to create a issue so I never said anything. I just wanted my car fixed properly and to leave.

Jose at Sierra muffler does quality work in less time than his competitors and at a fair price. Very professional and great communication. My catalytic converter was stolen out of my Honda accord and Jose did custom work to replace and repair my exhaust. I can’t thank him and Sierra muffler enough!

This is definitely the spot. The place to go where you want your exhaust system either have that deep ,loud tone... or if you just simply need some Muffler work or need Catalyst converters installed. These guys are very good at what they do. And fast at what they do. The shop is very family oriented, and will welcome you with love. Much respect for Sierra Mufflers.

Very happy with my experience. Very professional workers. Got a custom exhaust on my Subaru Impreza and let me just say, they did an amazing job getting the fitments and welding done correctly. I waited a few days to see how the new exhaust felt before submitting a review. Also, the pricing is very reasonable depending what you’re getting done. I would come back again with my other cars. Thank you!
