QUALITY SERVICE! Shout out to Louie who walked me through what was wrong with my car and was a huge help. He told me it would take 2 hours to change a sensor and he had it done in 1.5. He even showed me how to top off my oil and throw in a bottle. This place is the best! read more

3C Performance Exhaust - Auto Repair Near Me - Los Angeles, California

Just walked out to my car & found it jacked up. Someone tried to steal my catalytic converter again, but THIS time they saw the impenetrable cat cage Luis put on & said "nope" so fast they left their brand new jack behind. Thank you Luis & everyone at 3C. Y'all THE Best in town to guarantee your catalytic converter ain't going anywhere except for where it's supposed to be; on your car. The best $450 I've ever spent. I usually park on a busy street or this parking lot where I live. I've had this cat cage on for 1 year. This is just proof of 1 (out of I'm sure many) attempts to steal it again. read more

Very good job done by Peter Pann! Excellent work done on my Porsche 996. Gave me Porsche sport exhaust for low $$

Just like every other reviews here. Luis is a great honest man with realistic price that's upfront. Shop might be small, but no doubt they provide the best service in town! Instantly recognized where I had my previous work done from and fixed the sloppiness as well. read more

3C Performance Exhaust - Audi A6 installing bottled resonator - Auto Repair Near Me - Los Angeles, California

My catalytic converter was stolen earlier this week and I asked the shop that replaced it if they knew anyone who could put a guard on it. They sent me to 3C and whoever I spoke to on the phone told me, "guards don't work, we put a cage on it." Sounds good to me! I called the guys as soon as I picked my car up and told them I could get there by 5:20. They close at 6 so I was so grateful they allowed me to come in. The process was quick and we were out of there by the time they closed. Shortly after leaving, I realized I had left my sunglasses at the shop. I called at 6:12pm and THANKFULLY one of the guys picked up. He confirmed that my sunglasses were there and said he'd wait for me to drive back (which was SO sweet because I live across town and did not want to drive all the way back the next day). After sitting in traffic for 20 mins, I felt bad having him wait and called back to see if he could just leave them in a discrete spot outside. I'm not sure who I spoke to but he was happy to do so, and left them in a very discrete spot outside the shop, wrapped in a towel. To me, that's above and beyond customer service because the guys didn't have to answer the phone after hours, and they certainly didn't have to wait, but they made sure I got my sunglasses back. Last but not least, I took my car into my Toyota dealership for an oil change today and I asked them to check the catalytic converter + cage to make sure everything looked good and they said everything looked great. My only complaint is that I wish I had known about this shop BEFORE my converter was stolen. The price is incredibly reasonable and the guys are great 10/10. read more

I really appreciated their honesty. I definitely will come back when I need to. I don't know anything about cars. They could have easily charged me for what ended up being a very simple fix. I started hearing a noise from my car. It ended up being that I dented something underneath my car that wasn't serious at all and was easily straightened. read more

They helped put custom exhaust on my truck. New x pipe, flowmasters, headers, sounds amazing. Perfect welds read more

This shop is a great choice for all looking to get honest, professional, and fast service! Thank you ! For the great customer service.

Amazing service at 3C Muffler Shop! Luis, the owner, was extremely attentive and professional. They replaced my catalytic converter very fast and even secured it rods to help prevent future theft. I can't say enough good things about this place- highly recommend!! read more

These guys are awesome! I came in with an exhaust issue, they had multiple options and were able to get my valvtronic (what I chose) installed and even touched up the under side and tips for me. Only took a couple hours! Highly recommend them read more

Ruben and Luis tried to overcharge us, repeatedly telling us that if we paid cash we could avoid paying tax. But the amount of cash they requested was actually the insurance payout INCLUDING tax. Then they said that if we used a credit card their 'machine would automatically add 10% on top' of the insurance payout amount. Scam artists! read more

Came here after a recommendation from my new favorite mechanics over at Piechowski Auto. Needed a new catalytic converter and 3C Performance had me in and out the same day for a very reasonable price! read more

Luis the owner was super helpful and expedient on my 2021 Diesel Sprinter van. Custom work - no problem!

The best. Got a magniflow Cat back exhaust put on. They know their stuff Does quality work Very good price Knowledgeable. Highly recommended. read more

I had an awesome experience here. I needed a new catalytic converter after I became one of the many victims of the theft crime wave of those and Ruben said that they would handle it the same day and to just "come on down" to the shop and they would take care of me. I got a new converter and protective cage at a very reasonable price and the work was done the same day in a very professional manner. I could not be more pleased with my experience and would highly recommend them to anyone who needs their services. read more

I was victim of the latest thieves craze in that my catalytic converter was stolen. Only one company I called had the parts available in stock (I got lucky!!). They were quick and kept me in communication about the completion. The whole job was actually less money than I was told at the start. Awesome job and highly recommended if you can there. ** I would recommend buying the catalytic converter theft protection from 3 C's PRIOR to being a victim. A few hundred dollars for protection is a better price than a few thousand everyday. read more

I have brought both my cars here for the last 2 years. Both for custom x pipe cat back exhaust systems. Mark my words Luis and his team are top notch.. hands down. Not only do they build beautiful custom performance exhaust systems from scratch but they do it for a good price. No where else in LA will you get this calliber of work at this great of a price. Don't waist your time anywhere else go see Luis you'll thank yourself. read more

Louie the owner is by far the most patient and easy to speak to about your exhaust needs . By first impressions you can tell he has been doing this for very longtime , he was able to give exactly what I wanted before I can even tell him . He gave me exactly what I wanted and I've gone to more than 10 shops asking the same thing only 1 other shop was able to give me what I want but they wanted to keep the car (hell nah) . The price and the time it took to finish the job was less than 2 hours ! This man and his team are more than skilled and efficient. Pay the man for the quality of his work don't haggle because any other shop is going to mess up your exhaust. Louie is man of integrity and will not let you leave without making sure your car is how you like it. Bring cash better than card ! Thank you Louie for your service ! Que dios lo bendiga ! read more

Lois is the man! He helped me a ton with my 1980 toyota pickup. He is a genuine guy and this is a shop that you can trust. Thank you to the team again, these guys are fast and great quality! read more

3C Performance Exhaust - Auto Repair Near Me - Los Angeles, California

After our Prius had its catalytic converters stolen, Louis & his team replaced them quickly, efficiently and for a very good price. They included the fabrication and welding in place of stainless steel rods as a kind of cage to prevent them from being stolen again. (YouTube videos say that theft, then re-theft of converters, especially in Prius' is common! In fact, I counted 10 Prius' at 3C being worked on each time I was there!) They also helped me communicate the claim to my insurance company. Later, to prevent the 3 separate catalytic converters on my Tahoe from being stolen, I had them install a cage over each of them. The price was well below the cost of my insurance deductible, so it made sense financially, as well as preventing the hassle of having to make another insurance claim and organize replacement, etc. after a theft. I strongly recommend having them install the converter cages over your catalytic converters to stop thieves. I highly recommend them for any sort of exhaust repair. They have expert welders and can handle any kind of vehicle or exhaust system. And they are really good people! read more

Came here to installed the new exhaust system for my g82. Jose took care of my car really well. He solved all the problems during the work very smooth. Thanks man, you're my life saver! read more

They will rip you off. I had an attempt on my cat converter that sounded like it was stolen. I brought to them to replace. I waited an hour to even be seen after making an appointment. They put it on lift to inspect and found out that the thieves who attempted to take it only loosened the bolts enough to make it seem like cat was gone. It took 5min to put on lift, inspect and to tighten the bolts back. He charged me 90.00 because I wouldn't have him put on a 300.00 cage. Instead of making a long time customer and saying have a nice day. I have many cars could have done some custom works. Instead Im here trying to save someone else the headeaches and rippoffs from this poor business to the community. read more

I got a muffler delete done here and I'm really happy with how it turned out. The car sounds way better now--loud but clean, just how I wanted it. Louis is the guy to go to. He knows what he's doing, super easy to talk to, and got everything done pretty quickly. Definitely recommend if you're thinking about doing exhaust work. read more

Ruben and Luis! That's all you need to know! They get it done in a timely manner at a reasonable price. Had catalytic converter replaced! And a cage put on! Fast turn around! Fired Up!! read more

Louie was very professional and friendly from the phone call to the check out. He got me in next day even with a more complicated muffler replacement. The total repair time was quick, a little over an hour and the price was fair. If you need a muffler replaced I highly suggest trying these guys out. read more

This place is THEE SH!T ! Awesome service and customization of your system that you CANNOT get out of a box. I've had my truck worked on twice now by 3C Mufflers and I won't go anywhere else. I have to drive 40 miles to get to this shop. But they are SERIOUSLY worth it! I normally give a cash tip to the crew that works on my ride when I'm having work done. Their work is so good that the 2 bays with ramp style lifts ALWAYS have vehicles on them. As well as the apron area outside of the service bays having vehicles waiting AND vehicles lined up in the very small and narrow access road that runs in front of the shop and around the side to the east. Then south to La Cienega. Thanks to this access road. It actually helps you exit the shop due to the heavy traffic that is stopped at the intersection and red lights at Washington/La Cienega Blvds. Seriously recommend 3C Performance Shop! 5 Star rating all the way! read more

I had a huge hassle with a locknut which was broken off/the key broke. After several attempts to find a garage to fix it, Mario at 3C got the job done. It took him one hour to weld a piece on 4 locknuts and remove them!! My rims did not get damaged, they even cleaned them afterwards, it was quick and inexpensive. While I waited, I saw that it seems like a lot of ppl with extremely nice high end cars trust 3C as well. I'm very impressed and getting a decent price as a woman at a garage doesn't go without saying. Mario you made my day! Thank you read more

I have known Luis and the team for over 10 years now, and can highly recommend 3c performance exhaust for all your exhaust work. They are a highly skilled welder and provide one of if not the best services to the LA community and more. I had a unique situation where my 20 year old car had the muffler rusting out, and I wanted to refresh the look and sound. The team installed a quality exhaust for me while remaining under 93db's. Unfortunately, my rear sway bar kept hitting the exhaust so Luis was able to show me what he could do to customize the direct bolt on exhaust to make it fit without it hitting anything. He made my exhaust that fit ok, to something that fits perfectly with no rattling. I appreciate Luis and the team here, it's always a pleasure coming here to see the folks. I highly recommend 3c for all your exhaust needs, this refreshed my soon to be classic 20 year old car to now look like something new, especially from the back. On the floor is the rusty old oem catback being refreshed by a shiny new one getting ready for a change . There is also a really cool Black Mamba Champion painting which I highly recommend taking at a look at! Thanks Compas! read more
