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.

Louis and his 3C Team did an excellent job securing the catalytic converter with a custom-built cage. The cage, made of stainless steel rods, essentially makes future theft impossible. Princing... was fair. Just right. I’ve read that theft often happens more than once — once they know where your car is, they’re likely to come back. Louis is so confident in his work that he told me: “Ben, if your catalytic converter gets stolen again, come by and I’ll replace it for free.” When I called to make an appointment, Louis simply said: “Come down any time. We’ll figure it out and get you out in less than two hours.” True to his word, I was done in just 55 minutes. Louis, the owner and operator, truly cares about his customers and does things right. In fact, my invitation to Louis and his crew still stands — come by any time, you know where I live. Tacos and beer are on me!

I had a huge issue with my toyota prius and so I had to call this guys multiple times to get some advice. They answered every single time to all my questions in the nicest way. When I got there they put the cage on my prius’s catalitic converter, they showed it to me, explained everything about it, what they did and why. Their service was magnificent, their attention was lovely. It’s so nice when you find good hard workers that just want to help you with all they know. If you need this service I would 100% recommend this place. And super reasonable price!

I am a woman and I was navigating my search for a mechanic cautiously, hoping to not get screwed. I needed help with my catalytic converter and I didn't have a lot of extra money. I was recommended to this business , told that Luis was excellent, and loved the awesome reviews so I took a chance. Luis made the most rare offer, secured with a one year guarantee. I am very happy with the results and the price. I thought my car was kaput but now I know I can get at least one more year out of it. For the first time in life I feel like I found "my mechanic", which makes me proud, happy, and I feel safe. Much love and many thanks to Luis and the 3C team.

3c did a great job installing the valvetronic mufflers on my Mustang. My car has a full custom exhaust from factory and the guys here were able to fit everything up while keeping the factory look. Not to mention it sounds amazing. I absolutely will go back here for any future exhaust mods. The service is also great and the install was fast.

Took my 59 here to get new mufflers I had bought. He suggested a whole new pipe set up as mine was shot. I only knew once it was up on his lift. I have to say, the owner and Mario were awesome. Plenty friendly, knowledgeable and the price was more than fair. Quick turnaround on the day and the new setup looks and sounds awesome! Will definitely come back when I need to and i have e suggested to others to do the same. They get super busy so turn up early! Thank you!

Luis was awesome. He took us in right away, he was efficient and listened to exactly what we needed done. We have a large vehicle (shuttle bus), no one else really wanted to work on it but he said no problem. Our exhaust is really rusted but he wasn’t able to help us at a really good price.
