I called the day before I showed up. They don't really take appointments so it's first come first served. I was there waiting at 7:30am. They open at 8:00 and I was on the road at 9:30am. Armen was great to work with. Extremely friendly and offered something to drink while I waited. Mario was working in the garage doing a muffler delete on my Mercedes. Mario is a master! I told him he was an artist and did great work! The pipes were custom bent and installed like the pro he is! Highly recommended... ***** read more

These guys took the best care of my ride. I was there with my older VW and had new cat, stainless exhaust and magnaflow installed in quick order. Honest and straightforward, reasonable price. Thanks! Inadvertently placed review at rancho speedway. I was in Upland. I apologize for the confusion. I will delete rancho review. read more

Fast speedy service! Was actually referred to these guys by another mechanic into when his machine went down! That says a lot! Would recommend this place to anyone! read more

Today I brought my 2001 Silverado in for a muffler repair and was worried that they might be price gouging me like so many others here in town . But Not Speedway Muffler! They put my truck up on the rack and did a walk through with me while pointing out a few problems with my exhaust system. As usual , I got a Great price on my new muffler and they even fixed my exhaust hanger - And - straightened out my exhaust pipe up front for one low price. Nice.. This place hasn't change a bit since they opened shop back in the late 1980's. I have been going here off and on for over 30 years now and I have always been treated with respect and equality. The mechanic and the service writer were both friendly and accommodating . Thank goodness some places like this are still here in town who can do business on a hand shake. It's a rare find , and you'll find it right here at Speedway Muffler! read more

Went to speedway on a recommendation from my mechanic to replace my cateletic converter. It's a small shop but really good customer service. The cost of the part was a fortune, but they don't have any control over that. They replaced the part and when the check engine light went on, the addressed the problem and replaced it, no questions asked. I recommend read more

Best muffler shop in Southern California. Armin was very caring with my mustang and went above and beyond to meet the standards he had as if it was his own car. Will definitely be committing to this shop for any future exhaust inquiries. Thanks! read more

I recently bought an AC Schnitzer carbon fiber rear diffuser for my supercharged 1998 BMW M3 convertible. The diffuser looks great but visually dwarfed the straight tips of my Dinan exhaust, which looked way too short. Knowing how rare and expensive this exhaust is, I bit the bullet and decided to have a local muffler shop cut off the straight Dinan tips and replace them with a pair of AC Schnitzer DTM tips. That muffler shop did its job but unfortunately, the new tips were crooked and one of them was touching (or torching) my rear bumper. I went back to that shop and as expected, they provided minimal help (i.e. stumping on my exhaust tips and turning a screw on my muffler hanger) and told me to go home, get a screwdriver, and play around with the tips on my own. I eventually found/stopped by Speedway Muffler and was quickly helped by Rome and Mario, who really took his time to examine the welding on my muffler; remove the crooked pipes; adjusted the muffler; and re-weld everything in place with a level. In the end of the day, the new tips look fantastic on my car! I watched the whole process and can confirm that for just $20 more than what I spent at the first shop, Speedway spent at least twice more time making sure that the tips are welded/positioned correctly than the first shop. Speedway Muffler gets an A+ for the effort, an A+ for the workmanship, and another A+ for a reasonable asking price. read more

I've been to many different muffler shops since I'm a mobile mechanic but Speedway muffler never seizes to amaze with quality and speed. I always come here for all my exhaust needs fix or replaced and I without a doubt send all my customers here even if they have to drive 20 minutes out. The service here is well worth the drive. The owner Rome is the nicest most genuine shop owner I've ever met and I will forever continue to come here for as long as I can drive read more

Speedway Muffler - Getting new pipes exhaust and MORE! - Auto Parts & Supplies Near Me - Upland, California

Definitely a satisfied client. Their customer service was top notch. Rome and his team are straight up with everything and their prices are reasonable. Got a Magnaflow muffler with dual exhaust tips and my resonator removed for less than $300. Great deal! Leo was the mechanic working on this custom job for my 2016 ILX. He made exactly what I had in mind come true. Great clean job, nice clean welds and completed in a timely manner. Keep in mind, I was a walk-in at around 9:45 am, no appointment, on a Saturday, and they got this custom job done in less than 2 hours. I was out of there by 11:30. Thanks again guys ! read more

I took my crosstrek here to get custom exhaust done. I was very worried it wouldn't come out perfect because I'm OCD. They did an amazing job! The tips are perfectly centered in the bumper. I couldn't have asked for a better job. And they were very reasonably priced. Highly recommend! read more

Went in with a rattling sound under my vehicle. I beleived it was the exhaust and probably a faulty hanger. Thery took my vehicle in and said one of the exhaust hangers were installed incorrectly. They fixed it and sent me on my way with no charge. Haveing a place that gives you honest service is important. Some shops try to sell you stuff when you dont need it. Thanks. read more

The quality of work and customer service here is incredible! I had Magnaflow Performance mufflers and black exhaust tips installed for a great price that was more than half the price of purchasing the equivalent kit from Magnaflow directly! Also, I had an x-pipe installed improperly by another shop and they were kind enough to point out the mistake and fix it free of charge! That just shows the excellence in their work! read more

This shop used to be good when it was ran by the dad, now its garbage. Leo butchered up my custom exhaust. Went back for second repair. He was mad do to his messups. Had to go somewhere else to get it done right. Super tek in Glendora is by far the best muffler shop. read more

Installed my Borla s type cat back on my mustang in less than an hour! Awesome service!!

Does really good work and the prices were fair. I will be having my headers installed here in the near future

I called this shop back on Christmas Eve because a different shop that was referred to me was already closed at 2 pm. I was looking to have the resonator removed from my wife's Chrysler 300C. She wanted a throatier sound without blowing the budget. It was such last minute I had very little hope of getting in, but the guy who answered asked me when I could get there. I told him I was on my way! When I got there I was met at my car by a tech who pulled it in right away. They pulled the resonator and replaced it with a straight pipe quicker then I could finish the paperwork! I am calling them back today to get a new cat-back system for my Dodge Ram 1500. Great service, great work and a reasonable price. read more

I had replaced my stock exhaust with a catback system. I found there was some rattle during idle and low rpm range while moving. The rattle was annoying so I knew I had to get it fixed. I took my car to Speedway Muffler and I was on my way in about thirty minutes with no appointment. They were able pinpoint where the rattle was coming from and solve my issue. Initially the tips/mufflers were somewhat loose, but after my visit they're stiff with minimal movement and zero rattle! I'd definitely return without any hesitation for any exhaust needs. read more

Speedway Muffler - Flowmaster American Thunder cat back exhaust. - Auto Parts & Supplies Near Me - Upland, California

I've been to many muffler shops over the years and I highly suggest Speedway Muffler in Upland. Took my BMW 530i to replace a stock muffler after installing an M-Tech rear bumper. The stock set up needed to be replaced. The guys took the time to suggest a few options and I ended up choosing a straight through MagnaFlow muffler coupled to a nice stainless steel tip. Work was performed and I couldn't be happier with the results. Excellent work and at a extremely fair price. read more

Called in at 8am and spoke with Mario. He was direct and to the point. Brought in my 2015 Tundra and had them put on a Magnaflow with a custom dual exhaust. He charged me $475 and it took about two hours. I am very happy with their work and will defiantly use them again. read more

Brought my 1974 scout ii in today to have a complete exhaust done. Couldnt be happier with how it came out. Did a fantastic job with both my truck and my dads 74 bronco (bronco was done here twice, not due to any fault by these guys just wanted a quieter muffler. Guys swapped it out no problem) nothing bad to say about these guys. Great prices as well. Plan on coming here from now on. read more

Speedway Muffler - 2 into 1 magniflow exhasut. Came out great - Auto Parts & Supplies Near Me - Upland, California

Excellent work for a good price. Who could ask for more? I had a bolt on cat back system installed and the old one removed. I had gotten a couple of quotes from other local guys and their prices were ridiculous. Thanks to the guys at Speedway for doing an awesome job for a third of the price! Not only would I recommend - I am bringing my classic truck back for some work too! read more

This place does great work. Took my 67 Impala to fix that another place screwed up. I take all my cars here.

I originally went to Advanced Muffler to get my flowmaster 40 series installed on my 2014 Mustang. They did a terrible job! A hangar even broke off less than 1 month of having them installed. I ended up taking it to Speedway Muffler and Rome and his team were quick to notice the terrible install job without me even having to tell them. The Advanced Muffler install was so bad I decided to switch to magna flow with 4" tips and I couldn't have been happier! Rome and his team installed perfectly, it literally looks OEM with how he welded the tips onto the mufflers them self. Install was quick and I no longer heard the vibrations I was hearing with the terribly welded flowmasters I had originally had installed. Definitely coming back for them to work on my 2010 Cobalt SS. read more

This place has the best service and prices I've ever came across to out of all the other exhaust shops I've been to.. They converted my single exhaust into quad exhaust on my 2013 c250.. It looks amazing I've gotten a lot of compliment a on the sound, looks and quality.. Thanks guys your the best!! Romik did a great job on the Benz!! read more

Hubby doesn't have a yelp account so asked me to get on here and make sure everyone was aware of how awesome this place was! He was told at other places he needed two different things. Speedway told him the truth without having him waste money or sell him things he didn't need. Even things they recommended, they shared that they weren't necessary at this time and he could get them done later. This place is awesome per my hubby! Not out to rob you blind. Just great work at a fair price with awesome customer service. My Hubby is definitely going back. He trusts them to help maintain his vehicle. And the fact that he is no longer complaining about his truck, I'm ecstatic! read more

I had a broken muffler bracket and they fixed t faster than I could check in to Yelp. Very nice guys!
