Muscle Tuner Auto

My Mini Cooper is out of warranty and the engine light is on! It will cost me $ 179 to only do inspections in a dear store! So I searched this service store close to my place. It looks a little bit shabby and I was not sure if they can really help me. But it turned out super nice!!! A guy used a scanner and easily found the most likely problem which I just need to change a gas cap to fix the «oil leak». What a relief! I didn’t spend a penny and figured out there’s no big problems with my engine. They are professional and honest! Highly recommend!

Thank you MT Auto! You guys really know how to treat your customers right. Great pricing and excellent workmanship. Alex is very professional and very honest. His younger brother (sorry, I totally forgot your name) is very knowledgeable about BMWs and friendly as well.
Items that were installed: BMS aluminum catback exhaust system, H&R super sport springs, BMS intake, BMS wheel spacers, BMS charge pipes, and BMS tuning stage 1.
I can’t thank MT Auto enough. I’m really happy how my M4 drives now. I will definitely recommend them.

Took my 2013 WRX in to get Rally Armor mud flaps installed. Alex and Julio did a great job taking care of the work. I would highly recommend this shop to anyone in need of modifications done to your babies. Keep up the great work guys and thanks again.

I went to get a ⁵⁄₁₆ plenum spacer installed on my nissan z33 and was greatly satisfied with the end result! The throttle is more responsive now at 3500 RPM. Alex did a great job. i highly recommend Muscle Tuner to anyone in need of any bolt on needs or exhaust work. Their prices are very honest and everyone is very friendly! Worth the drive from San Diego !
Thanks Guys!

I’ve been here many of times for exhaust work and Alex is awesome. This is the only person who I let touch my exhaust. Thanks Alex! Highly recommended!

Tried to slam wheels that had no business going on my car into the wheel wells. A lot of shops refused me for fender rolling but MT had no problem, rolled them all without issue aside from something unavoidable due to a preexisting defect in my paint.
Headed back there this week to get some touch up work done — stay tuned for the results of that work! I’ll take Before & After Photos.
I drive here all the way from Silverlake — worth the trip.

This is place is good for installing exhaust systems. My friend bought a Borla Cat-​back system for her 2010 Dodge Challenger SE and this place installed it for $ 80, including the dual exhaust rear lower fascia. Next time I’ll check-​out their other services and paint jobs.

Okay, so Muscle Tuner Auto doesn’t seem all that impressive on the outside, but there job quality speaks volumes. They are friendly, honest and fair priced. Alex was very polite and professional.
I went in to get my calipers painted red and they did and outstanding job. Next time I visit they will be installing the MOPAR Fox Lift Kit on my Jeep Wrangler.
Oh and they are Military Friendly!

I wanted to cut out the mufflers on my CTS V before I got my full custom exhaust done. I went to this shop so they could weld in the 3″ pipes from the resonator back. Although the customer service was good and everyone was really nice, the craftsmanship was awful. One side of the exhaust hung 3 inches lower than the other. Also the hangers for the tips looked hideous and vibrated anytime I started the car. Luckily I only used their setup temporarily. This shop is ok if you’re going for a temporary set up or have a car you don’t care for too much but I would stay away. The worst part was the guy telling me that he couldn’t bend the pipe evenly because the output shaft was uneven when actually he was not a good fabricator. My exhaust shop in Sacramento gave me a mirror finish and fixed this shops miscues. Again they seem like good guys but stay away if looking for a long term solution or anything custom.

Second time coming here to get a new California approved catalytic converter installed. I couldn’t be more pleased with their work and their service. Highly recommended for anyone who needs work with their exhaust!

The best shop in town to get your car sounding nice. Fair pricing with quality work. This is where I go to get all my auto needs done. I owned a 2015 genesis coupe 3.8L and installed all my lights, parts, and accessories here. Now, I drive a 2016 sti and get all my parts installed and ordered from here. Alex, David, Julio, and Angel are all great quality service providers.

Alex and Julio are so nice. I had backed my car into a storage cabinet and the back was smashed in. It was a leased car so I knew I had to get it fixed before my lease ended. I was worried they wouldn’t be able to get it look like new again, but they did! At a great price too! I’m still not sure how they did it but it looks like nothing ever happened. They also fixed a sharp dent on my front that other shops said would be difficult to fix. Thanks again guys!

went in today to have ford racing lowering springs installed on my 2015 mustang gt. alex and the crew at mt took the time to make sure it was a successful install. they even cleaned up my brake rotors because i got some over spray from painting my calipers. the ride home after the install was good and felt the difference in springs. my mustang looks even better now!

Brought in a company vehicle because it died on the road.
Alex took excellent care of the vehicle. He called with updates on the maintenance progress and was so courteous and polite. After all was said and done, for the amount of work being done, the cost was really low and the turn around time was fast!
Overall great experience, which is a rare thing when it comes to vehicle maintenance.

Outstanding service! Friendly, professional, attentive, family owned business, which is service oriented. It may not be the prettiest shop, but it’s old school & clean. they have Very reasonable prices & do a great job.
I had to wait longer than expected & the job took longer to execute than quoted, but that was due to getting the job right. The wait was due to the job ahead of me, dual exhaust on a Camaro. Needless to say that’s a lot if work. My car required a new Cat. It required them to cut out the old one since it was welded and grind it to fit. After all the work I had a leak in the exhaust. Alex, the older son, took the the time not only to explain the problem & my options, but showed it to me. The final job, the exhaust tips are better aligned than originally!
I’m definitely using them again. The younger son, Angel, will be installing my stereo.

This is place is good for installing exhaust systems. My friend bought a Borla Cat-​back system for her 2010 Dodge Challenger SE and this place installed it for $ 80, including the dual exhaust rear lower fascia.
I came here to install my MOPAR by CORSA performance exhaust for $ 60. I haven’t gotten other services, but I’ll look into it in the future. As far as the Body Shop is concerned I do not see an area for curing, for that service I would go to another place that would guarantee their work; but to each their own.

I needed a place to have my used Magnaflow exhaust installed. I searched around USC campus“Master Mufflers” wanted $ 100. A shady place on Vernon and Hoover wanted $ 45 but I spoke with «Muscle Tuner» and they were very professional. The young man in charge of the shop named Alex, charged me $ 55 to do the work. They did a great job by adding extra pipe strengthen the exhaust give it the right fit and made solid welds.
I’m glad I found this shop. They have helped me to continue saving money on any auto repair needs.
