Adam and crew always do a great job for us always happy to referee people to them -keep up the good work guys!

Spoke to Brad over the phone for a couple days before finally taking my car into see him. Unfortunately did not meet him in person but he was very very honest with pricing, the work that needed to get done on my vehicle and was also very friendly and knowledgeable. I felt absolutely no pressure from him. Allan would also be answering the phones and I was able to talk to him a couple times. Both mechanics KNOW THEIR STUFF!! Both do not pressure, are so very welcoming and friendly and most importantly are honest. Allan and my family share a love for the Seahawks as we are all from Washington State "GO HAWKS"!!! I was glad to have met Allan when I came in to pickup my vehicle on March 18th 2026. My husband stated that our vehicle feels better today than it did these last couple of years, which says something great about this company and the people who work here. Honest business, knowledgable mechanics, friendly customer service and so many other pro's I could give this business and its workers. I am very happy that Yelp actually referred me to this place to have my car serviced. Big O Tires was where I initially had my diagnostic checked for my vehicle and they were trying to quote me an outrageous amount of money. Brad stepped in and was confident that he could get it much lower which he kept to his promise, there was one added service my O2 sensor that was not quoted in the initial quote but that's because I was only giving Brad all the information that Big O Tires gave to me and Brad went off of that and gave me a much lower quote. Even with the added service, Master AutoTech was approximately 1200 lower than Big O Tires. I will forever be a customer here. Thank you everyone at Master AutoTech my vehicle is running like it's brand new again!! read more

Came in because I see their sign about being catalytic experts nearly everyday. The guy at the front desk was super friendly, and was able to give me a quote and some information pretty quickly. The quote was also cheaper than other quotes I've gotten at other shops. I will be coming back here when I'm ready to get the work dome read more

I've used these guys a few times now and hadn't left a review until now until I tested the waters. First time I used them I had the catalytic converter replaced on my Honda Element this spring and it's good but, ended out having issues with a new throttle body I'd had replaced after they cleaned it when they replaced the car converter. They didn't charge me for having to replace it again and it's taken a few visits to resolve the problem but they have remained professional and held their integrity and earned my future business by not disregarding a new pain in the butt customer with a difficult issue! I will definitely refer family and friends to them. I appreciate your professionalism and patience. Thank you! read more

We have been coming here to get emissions done on our vehicles since we moved to West Valley. I love the 1 stop shop. We can get emissions and pay for registration without an extra charge. Thank you! read more

I needed a new catalytic converter and starter, I called a lot of places and they were telling me it was going to be days before I could get in, but this place said bring your car tomorrow and we'll take a look. They told me exactly what I needed (which I knew) and a few other things that would help my SUV run better. Everyone there was so helpful and explained everything thoroughly! I didn't feel like they were trying to take advantage of me or anything like that. It was expensive but I already knew it was going to be. My car was ready that night but I wasn't able to pick it up before they closed and I got it first thing the next morning. Again, everyone was so kind and helpful! I totally appreciate places like Master AutoTech because they seriously saved me from a total meltdown! Take your car here!! They know what they're doing and they're also awesome!! read more

Not only were they quick to answer my call and give me a quote on a wheel bearing for my vehicle, but they also fixed my car quickly! The employees are suppppeerrr nice & they didn't try to up sell anything else (which is super rare if you're a woman going to a mechanic. they assume you don't understand how certain things work and try to tell you your car needs additional unnecessary things & they are often super pushy.) I'll be back when my car needs additional work. Their prices are also the best. With low prices, high quality work & great customer service you can't go wrong with them! read more

I want there not long ago because my break was making a lot of noise. I put a new break a day before but I don't know why it was still making noise. They said I need new pad, rotors, and calipers. And asking over 900 $ for that! I decided to not do it went back home to check what was making a noise. Turn out it was my old break was stuck in the rotor and making noise. What kind of shit is this. The guys who work at the Master Auto Tech know but decided I need the hold shit fix. I just removed that by my self with a stick (a fucking stick) and the noise was gone. Everything work fine and no nothing. I don't recommend them. They are there to scam to people who don't know anything about cars. read more

Dodge vehicles are too complex. This is my personal review on one and last time. Just take your dodge to dodge dealerships. My check engine light was on, code was for oil pressure. It was my oil pump. They told me they checked everything was working well and told me to go to a dodge dealership to get the check engine light cleared. I spent 175 to clear it. That same day driving back it came back on. Annoying. Had to spend an additional 100$ to diagnose the problem. Other times I been here for oil changes, A/C problems, compresor problems, basic stuff and they were good. Nice staff read more

I am responsible for the care of our corporate fleet, and Phil is one of the best managers I have had the pleasure of working with.

I am NOT impressed with the office manager. If the company really does not need the business why can't I get honesty from him? Is honesty really that illegal? Why did he make it sound like it would be months to get an estimate when I called, then when I made the mistake at coming in he refused to be professional to come in to see what was wrong with my car. If he hates his job that despretely then he should find another job. read more

I have a pretty urgent car emergency. My car was leaking out nearly all of its oil when I pushed on the gas. I was referred to this Master Muffler and now I know why. My car was fixed within 24 hours and the customer service was amazing. Thanks Adam and the team at Master Muffler for making a very stressful situation less stressful. I am so grateful. read more

well it wasn't bad work I would give a easy 5 for the weld on my flex pipe, but they are charging way to much, I do not recommend going here too do it, the parts I needed they were charging 2,500$ for 500$ in parts, I would say just do it yourself, saves a extra 2,000$ dollars, seems like they look for the most expensive parts they can find, they as well made me pay 960$ for a flex pipe, and a used plastic fuel tank, they didn't even do everything I asked, as I asked for my exhaust leak fixed, (new) fuel tank, and a muffler resonator delete, I would veryy highlyyy never recommend this place to anyone. Great customer service and very nice people but there prices are absurd read more

I'm always so hesitant to go to auto-repair shops due to the anxiety that comes with not knowing much about cars. The repair staff here was so respectful, honest, and quick. My mom's car had been in really bad condition with what we thought was a transmission issue. However, it was actually something with the brake release and they were able to catch that super quick with accurate an accurate diagnosis. I am super thankful for the team and the service we got made us more than content. I would definitely recommend it here! read more

Friendly, honest and quick service. I didn't feel rushed and surprisingly, no mansplaing occurred haha. I had a few issues with my brakes and the man in the office explained everything clearly and kindly to me so that I understood exactly what they were repairing. Thank you for helping me with my brakes and for being kind while doing so! read more

Went in to get my vehicle emissions tested and it was a quick, painless process and the staff was incredibly friendly. I'll definitely be coming back for future services. read more

I love these guys! They're honest. They don't treat you like a number and they're efficient. I made the mistake of going to another mechanic and regret it because they're definitely not like Master Muffler. :) read more

Great prices & friendly staff. Had a weird sound coming from vehicle and they diagnosed and fixed quickly. Can't go wrong with these guys!

I was really impressed with everyone here. As a woman, sometimes when it comes to car repairs you may be talked down to. But here at Master Muffler that wasn't the case. I was treated with respect. They repaired my car quickly and everything seems to be running smoothly. They even repaired a rattling heat shield for no charge! Thanks guys! I'll be back again. read more

I frantically chose Master Muffler. Adam was great, explained everything throughly and gave us options on how to proceed. Did major work and got me out in a day. Everything seems very reputable and honest. Great experience and glad I found them, I will be using them for all future services read more

I took my sons first car he bought to get the tail pipe fixed because whoever put it in did a terrible job. They gave me an honest estimate which isn't always the case anymore. Customer service was great and I was very impressed with how honest they were when it came to how long it would take. Sam and Kyle did a great job answering all questions and explaining why it needed the work. I can say this place is fair and honest and stands behind their work. Great job guys!! read more

Came in for some exhaust work, they gave me an estimate immediately and were ably to get me right in, work was started and completed quickly and I was back on the road. Happy with the quality of the work. Thanks for a job well done! GM in West Valley read more

Ever since the owners retired this place has had terrible customer service. I had my Truck towed here after a conversation over the phone about exactly what I was bringing them, a 1954 Ford fire truck. They refused to work on it saying that it won't fit their lift which means I wasted my time and money. Have to pay to take it somewhere else. The worst part was their nanchalant attitude. Kind of a shrugged shoulders sucks to be you attitude. Avoid this place. read more

I've passed by here so many times and since it saves me a trip from going to the one in Murray I decided to come in for an oil change. They have great customer service. Everyone is really nice. Will be saving a trip from going all the way to Murray and will continue coming here for everything else I need. read more

I have been to this and the downtown location a couple of different times with different vehicles. On each occasion I have left happy with my service and price. I have had exhaust,brake and diagnostic work work done. It is a good locally owned business. read more
