Super Tek Performance

10 out of 10 would recommend SuperTek very good pricing as well, Marcos explained what was best for my vehicle and fixed the damage from a previous shop I had visited with no problems. Definitely will come back in the future.

SuperTek is the place to go for all of your exhaust needs. I am extremely picky about my car and don’t just let anyone work on it. When it comes to custom exhaust work, Marco is the only person I trust to get the job done. He’s a very friendly and funny guy and his prices are very reasonable. He’s definitely a perfectionist and will take all the time necessary to ensure that the work he’s performing on your vehicle is as flawless as can be. You will never feel rushed at his shop. Very easy guy to work with.
Last time I was there, he built me a custom Y pipe that ends as a quad exhaust and the work was perfect! I don’t think any other shop could have done a better job. He has me as a customer for life. I come all the way from Orange County just to have him work on my car.
Give him a try, you won’t be disappointed!

This place is great! The guy is very friendly and helpful, he helped me find what I wanted and he did a great job! Now my car sounds real nice and I would definitely recommend this place. Gets the job done good and quick and it’s a nice visit. Check it out!

I was stuck in a bad spot but luckily I found Marco.
I recently did a engine swap in my datsun stuck and I wasn’t aware that a critical piece was missing (down pipe) most business would reject the job because of the amount of time and labor it would take to make one but Marco stepped out of his way to help me on Memorial Day weekend. He finished up the entire thing on Memorial Day. While everybody was off he was in the shop taking care of a customer that he never met prior. His shop is really clean, his welds and quality of work are incredible. I am forever a custome to Marco. Best service I have received in years… Thank you Marco.

Marcos has the best service anyone could ask for. He’s funny & kind and does exactly what you ask for. I came here for brand new quad exhaust tips and he ordered them and the next day they arrived and he installed them. He made everything look clean and perfectly aligned. Everything that I asked for he did & everything came out beautiful!

Came to Marcos after a previous shop did some bad welding work on a muffler install. Talked to Marcos about different muffler options and he told me to bring the truck down to take a look. Took the time to test fit a couple mufflers and decided on straight pipes. Awesome workmanship, great customer service, and great prices. He takes the time to explain pros and cons and genuinely cares about his customers and the work he does. This is my new go to exhaust shop.

If you are looking for an honest muffler shop this is the place to come. When I stopped by to make an appointment Marco said that he’ll take a quick look right now. He hoisted the car up took a look and had me look at the problem with him as well. He explained what was causing the problem (all of which were very minor) and in 10 mins he was done. I was a woman that walked in with my toddler and rather than duping l, which he could have easily done he was very very honest and saw that I had a little one waiting as well. You will not regret choosing this shop for good honest hard work. I will recommend Marco to all my friends and family.

My man Marcos!!! Took my 2012 genners in. No wait or anything. Make sure you call & check first because he does work by himself. Took about an hour but oh man the wait was worth it! My car sounds amazing! If you want your exhaust done right then come here. Price was fair not expensive as other shops. The man is honest & funny as hell! He took great care of my exhaust. Even polished it… Haha. Would i come back for other work? Hell yeah.

Originally came to Marcos to install an Invidia Q300 catback exhaust on our Subaru WRX. We were very pleased with the service. Very knowledgeable man who works by himself, very professional and makes all customers feel welcome and comfortable. The shop is clean and organized, the restroom is clean and available to customers and the prices are fair. Not to mention the work done is excellent. We had to come back to have our exhaust welded due to expectations not being met and Marcos gladly helped us out. His welding is flawless, some of the best work I’ve seen. The exhaust still didn’t meet our expectations so we returned a third time with a different exhaust. Marcos again brought us in, made us feel at home and did great work on the car. We love the new exhaust! Very pleased with the outcome and service provided here so we will be returning with our other car for another exhaust installation. HIGHLY RECOMMENDED!

I came here last week, last minute, and Marcos took my car in, no questions asked. He did an excellent job on installing my exhaust. I’m back here once again giving him more work due to his excellent service and work! You will not be disappointed. Thank you Marcos!

Called Marcos about an issue I had installing my exhaust, once I got to his shop he greeted me instantly and got my car up on the lift. Fixed the issue with no questions asked and at a decent price might I add.
Definitely recommend coming here for your exhaust needs. Thanks!

Came in to the shop to get an estimate for a muffler delete on my 2015 v6 mustang and Marco made me a deal that I couldn’t refuse compared to other shops. Marco is a really chill guy with a lot of experience and I would trust him with my car any day of the week.

Came to Marco’s shop after reading other Unilocal reviews. Marco is as straight forward as they come. He is very friendly and professional and went over several different options with me regarding my 15 Grand Cherokee. I was looking to hear that Hemi V8, but not to obnoxious. Marco could have easily sold me a set of mufflers and priced me for a full custom cat back system along with removing the resonator in the middle of the exhaust. Marco was straight with me and informed me that it would simply be best to remove the mufflers and keep everything else underneath. Instead of easily making the muffler delete and welding straight pipes to the back, Marco custom bent the tubing to match the underneath of my jeep. He welded everything together and welded back the stock tips. The picture says it all!
Great job Marco and I will definitely be referring you to anyone I talk to looking for exhaust work.

So my cat (catalytic converter) got stolen and I called this shop. Marco, owner of the shop was super friendly, informative, and honest — to sum it all up. He even let me use his truck so I can buy the O2 sensor that was stolen in the nearby auto parts store and also get food in In n’Out. I brought him food coming back cause he was such a nice guy. As far as the work done in my car, he installed a new cat converter (with a warranty) along with the O2 sensor for a reasonable price. All the spot welds looks perfect. He didn’t charge for stuff that I didn’t need. I definitely recommend this shop if you need if cat converter replaced or need some custom exhaust work. We need more Marco out there!

So I was tired of my Corolla sounding like a Prius when starting the car and driving. You know the sounds a Prius makes right? Just listen to the wind blow and that is louder than a Prius! Lol.
So I decided to purchase a little something something for my car to add a little sound while I’m driving. I didn’t even think twice of where I was going to go. Super Tek worked on my previous Corolla to add a muffler and did a great job, so I came straight here.
Marco, the owner, even remembered working on my older Corolla too.
So I decided to get a Magnaflow exhaust. They also have a wide variety of exhaust tips. I chose one for the exhaust.
Marco did a great job installing the exhaust! He was not rushing the install at all (even though technically they were already closed). He really did make sure that everything is perfect before welding some hangers to the exhaust.
Definitely happy how it turned out! It looks great and it sounds mean! It’s nice to shock people because they aren’t expecting that the sound is coming from a Corolla!
Will I be back? You know it! Definitely will keep Super Tek in mind if I need to add some extra grunt to the ride!

Awesome work. You have to see this guy work. Everything is like clockwork. He has a specific spot for everything and works quickly and efficiently. He is a pro and a perfectionist, which are must have traits for anyone who touches my car. I will be going here for life now and recommending him to everyone I know!

Marco is great! Had a really horrible custom exhaust job done by another shop in Covina and was unsatisfied. The moment he looked at the welds, he was horrified and then proceeded to show what he could do and showed me previous work he’s done. He did an amazing job, listened to everything I wanted done to my exhaust. If youre looking for great customer service, and quality work, come here.

The second I walked in I was greeted by the owner, Marco. Super friendly, very nice guy. I was looking around at his shop and amazed at how clean his place was. Every corner, spotless, all the walls had neatly organized tools. His office was immaculate, even the bathroom was super clean.
After he looked at the car, explained what needs to be done, and advised on calling the dealer instead of fixing it. Needless to say, he was sincere, did not want to charge me for something that he could have, and I appreciate that. Very honest individual, and now he has a loyal customer for life.

Excellent Service, excellent work, Marco does amazing welding and really explains in depth why and how he does things instead of just doing it. Got my Skunk2 Universal Muffler put on my EM2 and he did a clean welding job at a reasonable price. Will definitely bring my car back for anything exhaust related.

Marco is the man! He’s my go-​to guy whenever I need muffler/​exhaust things done to my car. He’s worked my on VW GLI twice already and in the past when I had a 2007 Honda Civic Si, he worked on it three times (kept getting better mufflers).
Anyway the last time I went to him was back in 2012 and I felt it was time to replace my muffler since I’m kind of fed up with the slight drone noise I get when driving PLUS the tips were filthy black, no matter how many times I clean, wax, sand, polish, even dremel the tips, they always end up black a couple days later. (Reason why they did was because I didn’t have a cat) but anyway I wanted another muffler that had a shiny polished canister to it and so I bought one and received it yesterday and went straight to Marco in the morning.
Let me tell you about this guy. Marco does not give you pressure or does not become a sales person to you, he gives his honest feedback AND also does exactly what you want. I wanted the muffler at a certain position and while my car was up in the rack, he was test fitting the muffler and wasn’t positioned at the spot I wanted it to but he found a way to position it and that’s from removing some hangers that’s attached to the car which hooks onto the stock muffler, well he removed that and was able to position it at the way I wanted it to. And once it’s positioned at the way I wanted it to, then there he goes, he went right to work and cut some pipes and bent it to go into the muffler. He also installed some hangers onto my new muffler in which it’s pretty solid. Took him about a little over an hour to do the work. And I’m really impressed and happy with his work.
Marco does great welds. The way they look are pretty clean, I’ve seen some welds in the past from other ppl but comparing them to Marcos, the other peoples welds look like crap. Marco’s work is really good.
His pricing is also pretty good as well. Of course if the task is a little complicated, he will still be able to do it the way you want but with a complicated task, more money will be involved BUT don’t let the stop you. It’s still worth it. I love my new shiny muffler. Plus the drone isn’t there anymore, I have a deep quiet tone on my car now.
I totally recommend this Marco if you are looking to get any exhaust work done to your car. Any type of vehicle. He will do it.
