Super Tuning & Performance

Tell you what, Koko is a great guy overall ! Helped me out with my exhaust in no time ! will definitely be coming back soon, would recommend him and this shop to Anyone I know that needs exhaust work done, as for other things I saw a dynojet inside too so I believe he does other work on cars as well. Thank you Koko much appreciated !

Couldn’t ask for a better place to take my car for repairs. Koko and Mark are very knowledgeable, thorough, super easy to work with, and very reasonably priced. From now on, this is the place I’ll be taking my car to have work done.

Really happy with the work. Very professional, good work and reasonable on price. Thanks again!

I highly recommend Super Tuning for all cars and all types of work. Mark & Koko are extremely knowledgeable, talented, honest, and extremely reasonable. They are a class act. I had a performance sway bar installed on my Jeep Grand Cherokee Hemi that they did for me in 30 minutes and what a difference it made! They will do what your Dealer will do for ½ the price!

There isn’t a better shop in LA then this place. Been going here since 2003 and I have recommended this shop to all my friends and family members. Prices are great, the work is done with perfection and efficient on time. Koko is a class act with all of his customers, he builds a relationship with customers before he builds a masterpiece with your car. Best exhaust work in LA.

It’s rare that you see a Unilocal page with a perfect rating and when you go in all the reviews are on point. Koko is the most humble automotive man you will meet. Koko and his workers are very nice and down to earth. Koko is a welding wizard. Got me up and running on my xpipe in no time. Koko did have to make a run for some supplies on his sick long board :-) now my car feels better in throttle and torque. This ia my second car ive brought to him and wont be the last. I will definitely come back to these guys again.

This place is amazing! I have brought all my BMW’s
To Koko and he always makes them sound to sick. Always will recommend this place to anyone that’s looking for great work and a crazy exhaust note. I have to give it to him true master of his craft I drove my 435i in with a normal sound and drove it out and it sounds like a monster. Thanks Koko for all the amazing work!!!

I’ve gone twice to this shop to install an exhaust on 2 different cars. They were more than helpful and did a great job with the installation. Definitely will be sending people to this shop for installs.

Did some exhaust work done today. Awesome work and customer service. Works with customers to find time to fit them into the schedule. Always a pleasure to work with.

This shop and its, I believe owner (Koko), is really one of the best finds I have had in years. I went off the reviews on Unilocal when another installer did a kind of bad job. Koko was straight forward and told me the truth from the beginning and didn’t push me at all to have the work performed. He just educated me on why I was having problems and let me know the best fix and the price for that fix. He was even cool enough to tell me that its really not gonna be much better. I just went for my second trip there and actually had work done this time on my 2015 Dodge Durango R/​T. He did an amazing job and you can tell that is how he does things on a regular basis. Super knowledgeable, super trustworthy and really just a cool guy. I am very happy to have found him and he will definitely always be the first (and last) place I go for any repairs/​modifications that he performs.

I’ve known Koko for at least the past 10 years, and even to this day, his work and level of professionalism never cease to impress.
l would not trust any other place to work on my car, and to say he goes beyond his call to do an perfect job, would be an understatement.
His work is well reflected on the rest of the reviews, not to mention attention to detail and skill set which rival high end brands such as Kleemann, meisterschaft, and even Renntech.

Its funny to me that its taken me so long to write a review. I started hanging around his shops with me and my buddies fibre glass body kit-​ted slammed imports around 1997 … LOL Koko … we need 2 mufflers for our 4 cylinders cauz’ ma body kit got 2 holes in the rear bumper LOL … this was the only place i knew i could take my car where i felt taken care of … i can’t even begin to tell you the countless cars this guy has worked on of all kinds for all different years makes and models … imports. muscle… i’ve even seen him build a turbo kit… long tube headers … very skillfull guy … if you can imagine it … he can build it …

Nothing short of 5 stars. Been going to Koko since before he moved to his new location. For the last 10 years he has taken care of me and my cars. Given me great prices along with his expert knowledge. They really care to help you get the most performance out of your car. I’d recommend everybody to him especially the high performance tuned cars. No job seems to big or small for him. Many times I’ll bring in a part for a quick tack weld or two and he won’t even charge me. That is some serious customer service. Thanks a million to STP and crew.

Koko is straight up! You come with your wants and he will give you a more than enough fair price on the work. He will address any and all concerns. From CA specific catalytic converters to intercooler piping, Koko gets the job done. Of course, in return he expects you to be straight up with him. Basically, no dicking around.
I went in to weld on some exhaust components and he gave me a cheaper price than anywhere else in the valley. Another great thing Koko does is that he takes your ride height into consideration. If he notices youre really low, he tries his best to tuck up the exhaust as much as he can. Another great reason to go to STP, everyone driving a lowered car knows ho annoying it can be when you break one or two exhaust hangers. If I hadnt gotten done the work done at Koko’s i would be pissed everytime I break a weld. But he is considerate and takes your car in quickly to fix the broken welds, usually at low or no charge. I always toss him an extra $ 20 just because I know his work is top notch.
100% would recommend to anyone in any car that needs some exhaust work.

I just recently had some work done here on my 2007 Mini Cooper S. They installed an intercooler, silicone hoses, pedals, a rear diffuser, and they did some fantastic custom work on my exhaust including a Magnaflow muffler. They even went out of their way to source a custom exhaust tip for me. My car runs beautifully and sounds even better. But the reason I’m recommending Super Tuning to all of my car guy friends is that they were just really cool with me. They stayed late to work around my work hours, offered great advice, and most importantly, they never talked down to me like some shops do. Koko and Mark were always excited and supportive and interactive. They went out of their way to make me happy, despite some initial scheduling hiccups. I’m really looking forward to going back.

Koko is one of the best and most honest mechanic I’ve met. He does his job very well and makes sure his work is the best quality. He installed pipes for my Dodge Challenger and they sound fantastic. If I had any future issues, He told me to come by the shop and he would fix with no charge. He also does a variety of different applications rather than just exhaust. I highly recommend this place. I’m sort of a DIY guy but this shop is the only place where I trust them with my car. Thank you Koko!

Koko and his crew are as honest as it gets. He’s an honest guy, cares about his clients, and stands behind his work. I got my secondary cats taken out and a new set of exhaust tips put in. He went out of his way to offset my tips for me, paint them, and even fix a broken hanger he found for free because he already quoted me my price. That’s the definition of an honest man. I come to Koko for all my needs and have even brought friends. Don’t be intimidated by the tuner cars in the shop. I’ve brought my bimmer along with my friends range rover here and he’s done quality work everytime. Keep doing what you do Koko!

I have taken all of my cars to Koko. He does great work and is an honest guy. He’s busy yes and while some people may think he is too expensive, he does the work correctly and doesn’t rush (at least based off of my experience). I don’t trust anybody nowadays but I will remain taking my cars here as well as recommending this place to others looking for a great shop.

had an exhaust leak on an E63 benz. koko told me to come right over. I was back in business in 30 min for $ 60. I’d go there again.

I found Super Tuning on Unilocal,and decide to go talk to them about the exhaust on my supercharged 4runner.
Koko was friendly, knowledgeable, and honest. He didn’t talk down to me for my lack of knowledge with exhausts, and he didn’t 545 to sell me on a bunch of unnecessary mods and crap. He instantly took an interest in my vehicle and what I had done to it, and asked where I wanted to go with it.
He didn’t try to push products that he carries, and even encouraged me to shop around, do research on the sounds of different mufflers, and then try to find the best price I could online and just bring the stuff to him for install.
Today I came back and he installed the muffler (Cherrybomb Vortex — amazing on the 4Runner) and AFR wideband gauge bung.
After watching him work, I can say Koko is an expert at what he does, and did a very clean install on my vehicle, even taking the time to paint my new exhaust with high temp paint to keep it from rusting in the future. In the end, I couldn’t be happier. Fast, quality work at a reasonable price…
And as I left he assured me, if I have any problem, at any time, to not hesitate to come back in. I’ll be sending all my friends here.
