    Cold air intake
    Maria O.

    First time I came here was to get some coilovers installed and a muffler delete; Alex was communicative with me about time and updates. I've been going to them ever since for any help and opinions I need as they are very knowledgeable and know what they are doing. I am grateful to have found people who are so reliable in all aspects. I recommend muscle tuner auto for any modifications you need. Thank you guys ;)

    This review is long overdue, I've been bringing my car here for 4 years now and every time was a good experience. To keep it short, their service is amazing and they are super communicative and open with what can or needs to be done and what it would cost. They make sure your car runs great and stand by their work. Your requests and concerns are always heard here and they take the time to explain the what why and how of things. You won't be sold a product or service you don't need. For context of my experiences at Muscle Tuner Auto: I have had various engine bolt ons and suspension parts installed and other specific requests like custom exhaust, aftermarket horns mounted in a particular way, a hardwired dashcam with a custom on/off switch, and others I can't remember at the moment. Any time I encountered issues or strange noises whether it was rattling, clicking, or clunking, they would easily diagnose and sort it out. Somewhere along the way I started coming for routine maintenance of things like fluids and filters. Don't hesitate to reach out for what you need and see for yourself how they do things.

    I couldn't find anyone who would do my exhaust swap. I called up Muscle Tuners and they swapped my intake and exhaust. The guys installed the Borla S Type on my stingray! The Muscle crew was extremely professional and knowledgeable! They delivered! My vette sounds amazing now! No issues with fitment on my newly installed parts!

    I tried to leave a question, but told me it was to much.... so I have a 2003 BMW 330i that I would like to tune with a possibly of making it a daul exhaust with the blue tips, and maybe a meater hood with door window panals in possibility a light blue carbon fiber, (3 car in neighborhood are identical, want mine a tad different),,. Is this something something you guys do and a qoute please? Yelp told me it was to long of a question, so its a 5 star, my bad. Will swing by tomorrow.

    Alex and his brother did a great job on my Mustang ecoboost. I was looking around to add some modifications to my mustang and not a lot of people around South Bay are good with muscle cars specially a turbo one. I called them after reading good reviews on Yelp. It was easy to set the appointment and everything was done accurately as I asked them to. They even assisted me to give me a Cobb tune 101. I wanna thank Alex for an awesome experience, I'm excited for future mods. I'll be back guys!

    They did it again! Alex and Angel worked on my E500 by deleting the resonator and straightening out the exhaust for a great price. They are honest peeps and go above and beyond to making sure customers are satisfied.

    Hks sqv blow off valve
    Jorem O.

    I brought my Infiniti Q50 red sport here to get some HKS Blow off valves installed. I was skeptical at first cause I did not see anyone else get one installed based off reviews but I gave them a shot and they did not disappoint. Upon inspection it was a clean job and they did not cut any corners and did everything correctly. I will definitely be coming back when I get my down pipes!! Thanks guys!

    This is a great and professional shop to go to, especially for tuned, modified and performance vehicles. I've had problems with other shops turning me down or messing with aftermarket parts because they refuse to work with them or don't have experience with modified cars. Shops like these are becoming more rare, but this one truly is a gem. My bf had been coming to this shop for his supercharged Camaro, so I gave them a try when I was in LA for an oil change. Totally reasonably priced and allowed me to bring my own oil (I am particular) and got it done in a timely fashion. I'll be getting another repair here soon as well which they gave me a transparent and reasonable price for. They are extremely knowledgeable and while waiting you can check out the many project cars floating around the shop. (At one point had a Datsun z swapped with a bmw power train).

    Recently had the pleasure of doing business with Muscle Tuner Auto. They did the custom exhaust on my 1980 Pontiac Firebird. Made my appointment ahead of time so I was just able to drop my car off ( I highly recommend you do the same ). Alex was extremely helpful and the work on my car was done quickly and nicely at a relatively fair price. They definitely deserve the rating they have here on yelp and I'll be doing business with them in the future.

    i am a owner of a 2005 c6 corvette i took it in after i had seen all their existing reviews and i could not be happier not only did they stay on top of updating me but they also did an amazing job. my car had a bad harmonic balancer which is a part that over time tend to wobble and cause internal damage that part is now fixed and so are others parts i will definitely keep them as my corvette mechanics

    Workers Ignored me and even closed the left hatches.

    Showed up and immediately felt like I wasn't taken seriously, all the employees just stared at me and made no intentions to help me. I get it, they were possibly busy. However, the lack of attention to detail for a serious customer is what caused me to leave the shop. I was standing there for half an hour and not one employee approached me. These men just stared as if I owed them money. Not cool. I went to get my Camaro SS 2018 worked on. I had lowering springs in the trunk. Instead of leaving a satisfied customer I left with a bad impression. Will never come back. Do not bring your car here. Very unprofessional and rude workers.
