Speedway muffler did a catalytic converter on my Corolla at a reasonable price and they were done at the stated time. I was happy. They have limited parking which makes getting in and out of the parking lot a hassle, but overall it was a pleasant experience and I would recommend them. read more

After a "nightmare experience" with my catalytic converter I stumbled into Yelp and read the reviews and decided to look into this shop in Upland. It was not convenient to have the car towed from San Bernardino but I did it anyway and it was the best decision I ever made. The price, product and service was unbelievable. I highly recommend Speedway Muffler in Upland to anyone needing exhaust work. Thank You Junior! read more

Thought that I would give Speedway Muffler a long overdue review. Went here after I needed to fix some rattling to my exhaust system. They addressed my concerns and requited me a new price after the fix...which was cheaper! Very honest individuals! Thanks Rome and the crew! read more

I had a spare tire kit installed on my wife's Escalade and it required the rear muffler to be removed and i called Rome after Chevrolet installed the tire kit and he said to bring it in and they would take a look. When i got there at 3:45 pm he said no problem and he would do it right then if i liked and he quoted a price and it took less time than he said and it was less than he quoted... who can knock that, plus they did a great job. Another thing off the "honey do" list and the Mrs. is happy. Thanks Rome Chris read more

Came in got resonators to get rid of drone. They did the work with an awesome price. They did it pretty quick too. Saw my friend over there too and he was getting work done and his car turned out pretty well too. read more

Took my 370z to have some work to it done that other shops couldn't and speedway muffler was able to get the job done and within few minutes I was a happy customer. If you need any exhaust work done, you should come check these guys out. read more

Good shop with reasonable prices. The owner is very nice and knowledgeable. I trust this shop many times over the previous shop I visited. Honest workers that do good work. Also took me in immediately on a Saturday, which is more than I can say about other shops! read more

This place is great place to take your car for exhaust needs. My familys been using this place since i can remember. 2002 expedition, 84 mustang gt, 05 mustang gt, 11 mustang gt, 96 camaro rs, 96 camaro z28, 2000 jetta are some of the cars that speedway has worked on for my family. With the upgraded exhaust they all sound really mean! (except the jetta which was only a cat instal) Prices are cheaper than any other local shop, and the service is pretty fast. Will definitly continue to take my cars there and recomend them. read more

As a resident of Upland, I try to find local businesses to do my business with. I have used Speedway Muffler in the past and went there today to get my aftermarket 5" exhaust system properly hung on the factory rubber hangers. Within 15 minutes they had corrected the problem, which meant welding new mounts to the shoddy ones that came installed on the exhaust system. Good, fast, reliable service, and all for only $30.00. On a previous occasion, they welded on a new tip for me at no charge. read more

I was looking around for aftermarket installing shops around Upland so I called Alonso's repair. They recommended speedway mufflers so I brought my Subaru BRZ to get my greddy evo3 installed and I am satisfied with the results. Friendly staff and honest people. read more

I show up with no appointment and upon arrival I am greeted well and asked if I need help. Within 1 minute my subaru sti is on a lift already being pre-accessed for my new downpipe and heat shield. Once I said yes, they immediately got to it and had me in and out within 1 hour. On top of that the gave me an awesome price for the labor. Thanks again Speedway Muffler! read more

I have a 2015 Grand Cherokee with a Hemi. I have been to several places trying to get the exhaust sound a certain way. I was recommended to Speedway Upland and Romo and his team went above and beyond to get it right. They are also very friendly and I highly recommend them. Very reasonable price wise also. read more

Great and fast professional work with minimal waiting for low $ money in my case. would definitely recommend speedway muffler if you need any exhuats work done. Staff are knowledgeable and very friendly, Mario helped me out on my 2017 mustang GT and his work was phenomenal. read more

I just got a Flow Master Super 10 installed on my 17' Silverado. Jr and Mario were both very patient with the selection process and they even allowed me to hear multiple types of mufflers before ultimately making my selection. They were very skilled and completed my install in 30 minutes. I will definitely be returning for any future needs and recommend this shop to everyone! read more

Great, dependable muffler shop!! These people will take care of you with great service and great prices. Also gives you a test listen (who does that). Definitely a muffler shop for others and myself for years to come. read more

I went here for a test pipe install on my 2006 Nissan 350z. The job itself isn't hard, just a pain to do without a lift. Decided to take it somewhere local since it was just a simple install. I called before I came in and i told the guy over the phone what needed to be done. And over the phone he seemed like he knew what was going on. He quoted me over the phone that it would be 50 dollars. I thought to myself wow that's a good deal. normally i'd expect it to be 70-90 dollars. I went to the shop and first thing i noticed was that noone was around.. i had to stand around for a good 10 mins calling for someone before anyone came and helped me. A guy came and asked me what i needed. I told him and asked me what price i had been quoted over the phone and by whom. Told him 50 dollars and i didnt get the name of the person. So they get me to drive my car onto the lift. Which is odd but it's okay since my car is pretty low and i'd rather drive it myself. After i get out of the car.. the Mechanic comes and start lifting the car while on his cell phone. About half way up i say my test pipes are in the car and rolls his eyes at me and lowers the lift. As take out the pipes he aggressively says. What are those?! then turns to the front desk and said how much are we doing that for? and finds out they are doing it for 50 dollars. Proceeds to curse up a storm and says no way we can do this for that cheap. The guy says let me call and find out. So im left standing in the bay holding my pipes for 15 mins while he goes to find out and says its going to be 80 instead. I was a little irked at this time but i was in a hurry so i said sure that's fine. As i sit in the waiting i can clearly see the mechanic working on my car. Doesn't take too long but in the mean time he's smoking while working on my car and tossing my pipes around. As he finishes and im about to pay. the front desk guy says if you're paying cash i wont charge you tax. I think to myself. since when does anyone get charge tax on just labor? they didnt sell me any tangible goods. I was going to pay cash anyways so it didnt matter. but i had asked for a receipt which of course he didn't provide me which i thought was shady. i know there are more than one location for speedway muffler. Needless to say this experience has left a pretty sour taste in my mouth. So i gave this place 1 star because they were competent enough to switch out my catalytic converter with test pipes. But ill will NEVER recommend this place to anyone or ever come back for that matter. read more

This is honestly the best place you can take your car to modify. I wanted to change my mufflers and i really don't know much about mufflers so the owners really helped me out and made my car sound amazing!! If you want to get mufflers this is the place to go. And if you need help deciding they are the ones to go by! I highly recommend them. I will definitely be referring people to them! Thank you speedway! read more

Hands down the best muffler shop I have been to. They did amazing work on my truck and they are very quick also. Great service and their techs are do a good job at giving you what you want. I would highly recommend them to anyone that needs anything from repairs to custom exhaust! read more

I upgraded my 2007 Mustang GT's exhaust system to a Flowmaster complete with x-pipe, and new tips. The car has a more aggressive tone, and more power. Mario did a fantastic job installing the upgrade... I am very pleased with their customer service as well. read more

I've been bringing my Alfa Romeos here for the last several years. Very fair, honest, and know what they're doing. I have more restorations to do and will be bringing those here in the future. read more

This place was a great! I started to hear a leak from my exhaust and sure enough one of the bolts connecting the cat to my catback had fallen off. I came in and the guys fixed it right away and even welded some cracks I had for no extra charge. Definitely come through for any needs you guys have. I'll be back! read more

I came into Speedway Muffler to get a flange connected to my exhaust. I needed a way to switch back to my stock exhaust from my aftermarket one when the smog time came around. I was greeted by Junior who I explained my situation to and we put my car up on the lift. He quoted me at a very reasonable price that was much better than the other muffler shops around. The employees scrambled around working on my car as fast as they could and were very friendly. The business had multiple customers coming and going as I waited and looked very satisfied as they left. The job took approximately 1 hour and everything looked perfect. I would recommend Speedway Muffler in Upland to anyone who needs work done on their exhausts for a price that beats anyone around. read more

These guys were priced (out the door, installed) at less than half of what I could buy the part for at AutoZone and ten bucks cheaper than parts alone at rockauto.com. I can't believe it! The owner is a really nice guy. And I am amazed at how fast they did it, faster than an oil change. read more

The flowmaster mufflers they put on my mustang gt sound horrible. They belt out some weird noise that sounds like a kazoo on steroids. Took it back to the shop and had them take a look. Of course the sound doesn't always rear its ugly head so they couldn't figure out the problem. Put it up on the rack and it all looked fine so they sent me on my way. Not their problem I guess???? Cannot recommend this place. read more

I saw speedway mufflers on "Yelp " and after reading the reviews I knew that this would be the muffler shop for my 2013 Chevy Silverado being greeted by one of the employees I asked him what was looking for and that being a magnaflow muffler he had suggested a few and I decided on the one I would like and the price was fair and reasonable for the work they had to do and making a single into a duel exhaust which they had did a great job of the entire job about 2 hrs later it was completed and it sounds awesome I couldn't be more happy I talked with Rome the owner he is friendly and professional great staff I would definitely tell friends and family to go see speedway mufflers without a doubt I give speedway mufflers 5 stars across the board thanks Rome and staff Ps thank you Yelp for helping me find speedway mufflers read more

Went because this place was HIGHLY recommended by my uncle (coming here for 20 years). Was in and out in 10-15 minutes.. Went to get my cat switched out.. At the advice of my uncle (who owns only V8s..) - I asked to get a new muffler, as the car has 150k miles on it with the stock one. The manager questioned the necessity for a new muffler (as I have a low HP 4 cyl) and advised me not to get it. He went for quality and honesty over making a quick buck. It Was refreshing to work with an honest mechanic. Definitely telling all my friends about this place. read more
