Josh immediately answered my call and invited me to bring in my vehicle so he could inspect a check engine light related to the catalytic converter. He thoroughly evaluated the issue and clearly explained several options for moving forward. I greatly appreciated his professionalism, honesty, and willingness to put the customer's best interests first instead of thinking purely as a salesman. I would highly recommend Josh to anyone looking for trustworthy and knowledgeable service. read more

**CONVERSION AND BREACH OF BAILMENT** Just got a new 2026 Mercedes CLE53. I purchased a full catback exhaust and decided to bring in my car to this shop to get it installed. Josh was the one who scheduled me over the phone and handled the installation. Originally he quoted me $250 but because he said it was more complicated than anticipated, he let me know it will actually be $350. He was friendly, transparent, and got the job done. I understood and agreed to the mark up and was happy with the work, so I even left him a tip. The stock exhaust is all one piece so Josh told me that I could store it at their shop and come back another day to pick it up. A few weeks later I was finally able to get a sprinter van to come pick it up so I gave them a call to give them a heads up. They let me know that the owner literally sold the exhaust "yesterday". He said the owner tried reaching out a few times to let me know, but I have my call logs that show otherwise. I will reach back out, and give the owner a chance to make things right. Brand new OEM CLE53 Exhausts are not cheap at all. If he does not try to resolve, I have a strong legal case in court. "When the exhaust shop agreed to store your stock exhaust for you to pick up later, a legal relationship known as a bailment was created. In a bailment, one party (the shop, or "bailee") takes temporary possession of property belonging to another party (you, or the "bailor") under an agreement. By selling your property without your permission, the shop committed conversion (the civil law equivalent of theft) and breach of bailment." read more

I'm not mad I just learn from it , I'll tell my Homies to definitely go somewhere else .. much love. read more

Came in with an exhaust rattle on the flex pipe on my Taurus SHO. Josh took my car in right away and was very helpful and showed me the problem area and also showed me some oil leaks I had not noticed before. He got the job done fast and properly and made sure to check his work after to verify the exhaust had no leaks in the welds. He went beyond that and painted the areas he welded to prevent rust. I tried to give him a tip and he politely declined, what a stand up guy. I'll be back for any other exhaust work or upgrades I need because of the level of service he provided, thank you Josh!!!! read more

I went in wanting to delete my resonators not knowing much about the exhaust setup of my car and Josh told me everything about the resonators with a free inspection he did as soon as I got there. He also gave me other options like an X-Pipe for a third resonator. After deciding what to get he had super competitive pricing so I said yes right away and he got to work. Within 20 - 30 minutes later he was done and I was driving home with a big smile on my face! I honestly wouldn't recommend anyone else! read more

Amazing and very quick service! Called a couple days in advance to ask for availability & they worked with my schedule.

Took my Land Cruiser with 300k miles in thinking I need new cats, no CEL and it passed smog, but I was hearing a rattle around the cats. Josh took it in right away, put it on a lift, diagnosed it, and figured the rattle is coming from the transmission/transfer case area. The Land Cruiser has four catalytic converters. He saved me thousands of dollars for new cats. I appreciate his honesty and prompt service. I drove 20 miles to their shop because of their reputation on Yelp. I highly recommend Muffler Tech for any muffler related work. read more

These pictures are taken after this muffler shop welded my exhaust. I don't care about how ugly it looks, but at least weld it properly. This exhaust was on the car during the welding. I noticed leaking air, so I took it off the car and realize how ridiculous this is. Not just leaking air but put my life and others in danger. read more

Love this spot! Josh is amazing! Super honest and hard working! A+++++++++++++++++++++

Found this place when my catalytic converter was stolen from my car. The reviews were very good and when I called to check, this place does do custom cages to deter future thefts. Armen was very patient in describing the situation for me and when I arrived, he was very friendly and thorough in giving me all the information I needed as to the process to get my car repaired through my insurance. His shop closes at 5:30pm and I'm a good 30 minutes away and he offered to stay and wait for me both on my drop off and pick up since I get off work at 5pm. Considering other shops that AAA pointed me to rejected me as they were no longer taking anymore catalytic converter claims and quoted a 2 week backorder, Armen was able to get me a replacement and back on the road in 4 days time, including the weekend. Armen really cares for his client's and was able to help me out on pricing for the custom cage he installed so that I hopefully do not get hit again. read more

Came by with a complete exhaust system that I wanted to have installed. Got quoted some exorbitant price and was told about weighing opportunity cost to work on my car as well as being questioned about the fitment of my parts off of visual inspection. Rest assured, I bought my parts from one of the more well known brands so I know for certain it would fit but when I felt gas lighted I doubted myself. Took myself to one of my usual shops after getting multiple quotes a few days later and had it installed with no fitment issues/modifications for what I believe is the industry standard for pricing. If we couldn't get work done the day of, we could've just left it at that. I felt put off by the price and excuses but giving 2 stars for their time to even consider the thought of the work. read more

This shop replaced the cat in my Ford Ranger. The price was reasonable and it was finished at the time that it was promised.

Just went over on my lunch hour to get a quote and next thing I knew. They started on my truck. Gave me a great quote and they said that they can do it right now! So course I jumped on it. They finished my QTP valve install since the company I bought it from (Amazon) set me the wrong one. They ran the wire far away from heat and then added a little more security to the plug by wrapping it with special heat tape. Also they made it fit better with the correct length bolts and did a cut on the turndown since it would have been sticking down to much. Highly recommend this spot!! Thanks again guys for the awesome work and the very cold bottle water! read more

I got a OBD2 code on my dashboard stating my driver side catalytic converter needs replacement and came to Muffler Technician via a reliable referral.

Overall, I was satisfied with their promptness, service, and expertise. read more

Came here because I needed a new catalytic converter welded on. Smog is coming due and found Muffler Technician on Yelp so I gave them a shot. Two words, blown away. Armin was friendly, informative, and explained the process step by step so I wouldn't have any surprises. The attention to detail was impressive. Mirrors to check for any missed spots(there weren't any) and he even went as far as using an ingenious tool to actually listen for any air leaks. Great service, quality work and a very fair price have earned them a new customer read more

There's a reason this place has a 5 star average rating which is hard to maintain! Brought in my Alfa Romeo Stelvio to get a custom exhaust fabricated and Armen went over my options in a honest and straightforward manner and allowed me to ask questions before I decided on the exhaust. They were able to get it done really quickly even though they're obviously busy due to all the great reviews and I couldn't be happier with their work. This is a business that not only takes pride in their work but have the expertise to do the job with precision and care. I appreciated their honesty and great pricing as well as their attention to detail. If I have any exhaust needs in the future this will be the first shop I contact and go to so give them a try first before you bother to go anywhere else! read more

The catalytic converter on my Prius was stolen and this place popped up when I was searching for a muffler shop. Armen was very helpful and made the entire process easy. Contacted insurance company to have the car towed to the shop, and the inspector went directly to the shop. From beginning to end I didn't have to do anything other than call my insurance to get the car over and then pick up my car once it was done. They even took a pic of my car when it arrived to assure me that it was there so I didn't have to go over there. Would highly recommend this shop if the same unfortunate theft happens to you. read more

thank you muster tech for hooking me up today. So I had my catalytic converter stolen from my Prius and I called multiple places multiple muffler shops and they all recommended to go through insurance. However, I only have minimum coverage which doesn't cover my stolen Cadillac converter. A customer of mine recommended muffler tech, and I called them right away. just off the phone call. I already knew I called the right spot. The guy answered every question where other places say you have to bring the car in for me to tell you this spot also said the same thing however they gave me complete of what I'm facing what I'm expecting once I arrive based on that one phone call I can really tell that these people are trustworthy so I ride away. Had my Aaa send my vehicle to their location. What's the vehicle arrived? I got a phone call and explaining details of what's going to be done on the car what also needs to be done on the car. What I love the most was that he placed himself in my shoes, understood my situation and worked with me on the price got a job done really fast and on top of all that he sends me a picture of underneath the vehicle showing the job he did and extra metal he welded on to secure the parts so no one steals it ever again overall im very satisfied. I'm very grateful that they're still humanity left out there. I highly recommend this location, especially for anyone that does not understand anything about cars. very thankful I will definitely recommend every single person that needs to muffler technician. read more

If you need any muffler services or a cat converter replaced. I highly recommend this place. My converter was stolen and as I called around to get estimates and guidance on next steps. I found Muffler Technician with their stellar reviews. Was a bit hesitant to all the 5 star reviews, but after calling and speaking with Armen. He wasn't pushy on me getting the car over to his shop, rather he took the time to explain what the process of going through insurance would look like, and if I wanted to go out of pocket depending on my insurance company. He was absolutely knowledgeable and professional over the phone, and so I took a chance and brought my car in for him and Josh to look at. I arrived and Josh immediately got my car up on the lift. Armen came out and talked to me, and again, just top notch customer service. Everything he explained on the phone in going through insurance actually happened. No games, just straight to the point on helping me get my car working again. The turnaround was insanely fast, and they even helped me get a cage installed to hopefully prevent another future theft. When picking it up. Armen was very clear on next steps in getting a new smog sticker (CA -emissions), and I will see him again to check my emissions before my smog test once I hit 150 miles on the new converter. read more

Today l visited this auto shop (just near my workplace) and the techician was very kind to check my car as l mentioned to him what happened. He did a detailed check and told me not a big deal so l release my worries. He even didnt charge me. Thank you so much! read more

This place will always have my business for exhaust work. Muffler started having some noise due to failed factory welds, and the day I called they had me come in, got me setup with a new muffler, took the time to re-enforce the factory welds for the new muffler and had me off on my way in 45 minutes. Thanks again Armen and Josh you guys always are so helpful. read more

Their whole system is awful. They ask you to call and set up appointments. I called up and set up an appointment. When I got there they only have 1 mechanic putting a muffler on a minivan and they tell me to come back Saturday. Garbage service and whack shop read more

I bought a used 2001 Acura CL that failed smog because the previous owner replaced the catalytic converter into one that does not comply with California law. Shopped around and was recommended to this guy. He quoted a good price for the price of a new catalytic converter that complies with California law and labor. Drove to this place within the hour and he worked on my car instantly since he had no customers. Since the catalytic converter was a universal one, he even cut through and welded a bung in the converter so the o2 sensor can be screwed on there. Anyway if you have need anything that relates to exhaust or mufflers go to this guy. Well recommended. I also passed my smog check too read more
