Ask any car guy in SoCal if they know Supertuning, if the know KoKo, and most, if not all, would say yeah. Ask if they would recommend, and again, most likely a hell yeah! Go here, trust me. If you are reading this, go here. Drop my name and said you saw my review on yelp, for real! LOL! Need anything done from stock stuff to aftermarket, it will be done properly here. Anything dealing with exhaust piping and/or mufflers, catalytic converters, intercooler piping made using mild steel, whatever you need, they could help or point you to the right people. Value is always good. Service and value are great here. I've been coming here for over 20 years! Trust me, this is the place to go to, always! read more

Just came home from my exhaust install. Excellent all around. Koko is a solid guy, knows exactly what he's doing and how to do it. Mark was there as well and handled the expert welding. I love the old school, let's do it right approach. My favorite part is when Koko actually cares how my mufflers sit, he checks and double checks and checks again to make sure it is straight and middle. I would come back for all my exhaust needs. Great shop! read more

Fast and friendly people. They were already closed at 5pm but I called and asked if they can fix my car at 5:10pm for an emergency fix. Coco was able to squeeze some time for me. Service was great and got the job done quickly as possible. Will come back soon for my future exhaust components needs. read more

Absolutely amazing mechanics Koko and Mark are pros at anything exhaust, suspension, and tuning related. Came for a res delete and was in and out in 20 mins and it came out perfectly. Great price too read more

It's been almost 10 years of going to STP and they are getting better and better every year. Always willing to make modifications work. Koko cut my bumper perfect to fit a muffler that was way to big and it came out perfect. All of this for the best price in town. Couldn't be happier. read more

Take your car here for anything exhaust or suspension related. True professional work. Koko is the man

Had a small hairline crack on my exhaust's hanger that was getting too noisy to handle, and Koko & Co took care of it with a quality weld in less than 15 mins. Fair pricing, clean shop, great costumer service. Mazda Miata '17 with a Cobalt Exhaust. Will be coming back for some suspension work. read more

Been coming here since 2006. There is no other spot I'd go to for exhaust related work. Had custom exhaust work done on various SEMA builds and builds that won a bunch of useless trophies in car shows back then. read more

My go to for our cars' exhaust needs. Great work/craftsmanship and they are very fair on the amount they charge.

I'm surprised I didn't write a review earlier. I asked Koko to make me a custom cage made from rebar to protect the catalytic converter in my Honda Accord. It got stolen and I wanted to prevent it from happening again. This seemed like the best solution as a deterrent. So I was pretty disappointed, or so I thought, when I started the car a year later to hear the sound of a missing cat. Only it wasn't missing...someone tried to steal it and got one cut into the pipe only to realize that it was going to be way too difficult cutting through the cage, so they gave up and left. The repair for the cut was pretty straightforward. Anway, Koko is awesome and I wish more people knew about these rebar cages to protect their car, especially if you own a Prius, a Honda Accord, or one of several other easy targets. read more

Called yesterday to see if I can come in to potentially do a muffler/resonator delete on my 2021 Civic Type R. They told me I could come in anytime the next day so I went, they removed 2 mufflers, did a sound test, and I liked it so I was out. Super fast, super easy, and was very affordable. They were also very knowledgable about exhaust drone and made me feel welcomed and at ease about what I was doing to my car. Highly recommended! read more

Bought a new exhaust on a whim and didn't know where to go. Called many places but these guys were the only ones whose photos on Yelp actually showed them doing work on regular cars on a normal lift. The price was pretty standard, I called about maybe 8 places in the valley and 4 outside, theirs was about the same. The only difference was that these guys did my exhaust in 15 or so minutes, maybe 10. Right in front of me. No "hey wait in the waiting room" or anything, you can watch them work on your car right in front of you. I got a Remark exhaust for my civic Si. If you guys read this review, great work, honestly was pretty impressed at how fast you worked. Other places told me it was gonna take like 2-4 hours, don't understand why really. read more

Not sure what else I can add to what all the other reviewers have already said! SuperTuning is the ONLY SPOT I will go to for anything I need done to my car (performance wise). KOKO the owner, is an exhaust magician. He and Mark are both extremely skilled. They are the only two people who will be working on your car - no lackey who doesn't know anything will be touching your baby. Welds are almost factory quality. Koko has all the parts needed to modify pretty much any exhaust to fit your car. There is also the "Koko Special" which is a completely custom-made exhaust! I personally have not gotten a custom made exhaust but I've seen a few and they were all consistent- he understands velocity, backpressure, etc so you will have the best flowing exhaust if you decide to go custom. Rasp is not an issue as he also has all different types of mufflers. There are also a bunch of different muffler tips to choose from as well. You can bring your own, and he will weld it on. (This applies to pretty much everything else too). I will be getting an extension welded onto my exhaust as it's for a Z - my car is the exact same as a 370z / G37 in everything except it basically has an bigger and longer SUV "shell" haha I have personally gotten 2 test pipes and a catback exhaust installed. He has LIFETIME WARRANTY on his work, so if your exhaust gasket cracks, he will replace it - you should probably get the Z1 gasket to begin with though lol. Currently on my 3rd SAME MODEL CAR (had a 2012, a 2015, now a 2017) as I love everything about it, the fact that it's NA, and the last of the VQ37 engines.... I have a long tube CAI, IS-R single exit exhaust and Y pipe sitting in my garage which will all be installed in a few days. Since I have only gone here since years ago, Koko knows me and looks out for me- but don't get me wrong, even as a first time customer he will not do anything shady like give you a pricey quote that almost every other shop would do. A few times he had his shop open past posted hours and still worked on my car. His prices are fair, his work speaks for itself, just check the SuperTuning Instagram to see for yourself. You don't need to pay triple the price to get something done at some Instagram famous spot, bring your car here and get the best work done for the best prices!! read more

THIS PLACE IS THE BEST! I have had my Lexus SC430 done and now my Infinity. Both jobs were done in record time and both cars sound like a lions roar. I'll be sending everyone I know who needs high performance work done to Koko. read more

Hands down the BEST exhaust shop in SoCal! Koko and Mark are true professionals when it comes to welding & custom piping work. I had been referred to them by a close friend who did a custom exhaust on his Audi and Mercedes, so I took my Mercedes to them for some custom piping work...man, I was more than impressed. The true professionalism, and chill attitude, is very humbling. Both Koko and Mark have been absolutely amazing working with me and waking up the AMG sound of my baby. I recommend anyone to come here if you want a custom-tuned exhaust for your taste! Thank you Koko and Mark! read more

Koko and the crew installed my AWE catback on my A5 and did it within 20 minutes! He has a wealth of knowledge in his craft and it shows and if he can't help you, he will send to other shops that can because he's well known in the industry and prices are reasonable. This won't be my last stop to super tuning. Thanks again Koko. read more

Messaged them the same day, asked for a quote and got an appointment with them all the same day. Got my exhaust adjusted and did it all less than an hour. Very professional and for sure been in the business for a long time. I for sure recommend going to Super Tuning & Performance! Just look for Koko! He'll get you and your car right! Thanks again Koko! read more

Koko is the man!!! After a terrible experience at another muffler shop installing my exhaust wrong I felt extremely weary about taking my car to another shop but I decided to take my car to STP to get my exhaust fixed. Koko knew exactly what to do and got it done within 2hrs. Koko and staff are quick, knowledgeable, and very meticulous in their work. His prices are great and include lifetime warranty. Rest assured your car will be in great hands. I definitely will be taking my car back to get lowering springs and other work done in the future! read more

What a great experience ! Koko knows exactly what he's doing, he's a no nonsense person and does great work! I know where to go for any exhaust work. Yelp does not misrepresent this place at all! Had Borlas installed on my Audi 3.0 and I love it! Thanks Koko! After the great job on my A6 I've come back to Koko with an S6, resonate delete and relaxed mid muffler with an X-Pipe. Koko is straight up, responsive and above all knows his sheet!! Anyone needing exhaust work, especially performance nuts... this is the place read more

This place is great , my son had an exhaust issue on his Atv ( they don't even work on quads ) and needed a little custom work done . I stopped by and the owner was there he took his time to understand what I need and asked me to wait . With in 15 min he fabricator flange and the problem was fixed . He even refused to take any money from me . Just goes to show you what a great person he is. Will use them again in the future if needed read more

************ UPDATE***************** 2 years since the initial exhaust install , I came back to Koko to install the AWE switchpath non - res exhaust on my ZCP M4. While it's a bit more complicated install than the previous car , Koko knew exactly what he was doing and STILL gave me an amazing price and WAY WAY cheaper than any other shop. I can not recommend him enough , save yourself the trouble of looking at other shops and come HERE. read more

These guys are the real deal. True Professionals. Any real car enthusiast understands the fear of going to an exhaust shop. Some shops are the shady chiropractors of the auto world. Not these guys. I could tell by the way they took the time to balance my MR2 on their lift at all the correct points (without damaging the frame like everybody else does), before even getting it off the ground to inspect - that these guys approach the problem with a higher level of respect to the work. I've had orthodontists give less attention to detail. They chased down my exhaust leak with the type of intuition that can only be had by experience. Exactly what I wanted; the definition of leaving it to a professional. I rarely leave positive reviews ... these guys didn't ask for it, but they deserve it. read more

Koko and Mark were super awesome with everything! They were very kind and polite! I felt in good hands! And boy I was right, job was done perfectly and as expected!! Great guys! I highly recommend! read more

Courteous professional and great attention to detail. Highly recommended! Even set a tile to come so I didn't have to wait at all.

My journey with this place started with my BMW 328i and brought all my cars here after that (STI, G37). I recently moved out of LA and out to the Midwest and although they got exhaust shops out here, Koko is so knowledgeable I would rather ask him because I trust him with my questions. Great work and they are always open to help. This place is great just wish I was closer to keep going there. read more

KOKO and MARK! Quick dual resonator delete done here, no hassle and great teamwork. The whole experience was new to me, but they were accommodating whole way through.

I know they do a lot more than just deletes, and watching them work is like a master working their craft. read more
