When you bring your vehicle here, rest assured you are in good hands. We found out the vehicle my friend drove had a bad cat. P0420 code. The smog place requested us to send car for repair. When she called Dago gave my friend a quote she couldn't miss. Helped my friend with a new catalytic converter at a reasonable price. The Service here is superb. If you need any catalytic/muffler/exhaust work done this is the best spot in Chino hands down. We will be back soon for more work to our vehicles and also spread the word. read more

Again, the staff here has no clue what they're doing. The girl in the back after 15 minutes didn't even start on my 2 combo meals and they're trying to tell her verbally what my order was. She didnt even understand the verbal order. Bad managers here. That's the problem. Its why I go to the other one 5 miles away. read more

Advance Muffler was quick and MUCH cheaper than the alternative. I had a 2010 Range Rover that needed a new catalytic converter. I found Advance Muffler on yelp and they were quick to respond. I tried searching for cats on my own and everyone said the only option was Magnaflow for $2100! Advance Muffler was able to weld on a California approved catalytic for less than half that. And it comes with a 7 year warranty. He didn't try to upsell me on doing the second cat but said run it as long as you can and come back whenever I need it done. This shop is honest and customer focused. 5 stars all the way. read more

November 25, 2022 I reached out to Dago from Advance Mufflers today to see if he can repair the damage exhaust system to my 2019, Toytota Sienna, (Wheelchair Van Conversion). It was no problem for Dago. He was friendly, knowledgeable, and provided a reasonable price to fix the exhaust pipe. The wait time was anywhere from 45 minutes to an hour. And, when the job was all done, the problem(s) to the van were eliminated. Thank you Dago for your hard work and for a Job Well Done. JT read more

If you've ever tried removing T50 torx bolts on a Jeep hinge, you'll know they're a pain to get out (even with a breaker bar). I ended up stripping two of them completely. Extraction kits were a no-go, but Dago and his staff were able to weld on a nut to get them out. Highly recommend them. Top notch service! read more

Worst service the 1st and 2nd time ! I just wanted them to abide by the warranty. Got the run around on that matter . Suggested we switch out old catalytic converter under warranty at the time , and replace with a new one. I agreed for this and asked for a quote. He never returned any messages or calls. I'm going elsewhere, but, whatever services & quality they once had, it's not there no more. Caution, if you step into the so called office, prepare yourself to go get a tetanus shot. Seriously, if you want bad service , that's where I'd go . read more

Great guy, treats you like a best friend, has pride in his work and won't have you leaving with any problems.

I have an elderly neighbor that recently had his catalytic converter nearly stolen as they were able to saw off one side and partially on the other. I saw the reviews for Advance Muffler and I gave the shop a call. Dago answered and he was friendly and welcoming so I decided to take my neighbors truck here. We are so glad we did. He was able to repair it and was upfront and honest and even showed us where the damage was. He charged a fair price and my neighbor was so appreciative of Dago and his shop. I highly recommend Advance Muffler and I will be definitely going there for any future needs and the same with my neighbor read more

First time visit to this shop based on the positive reviews. Now I'm another happy customer. Dago and Caesar are honest guys. They quoted a very fair price, worked carefully, and delivered on time to get me on my way. The shop is close to the 60frwy and has easy parking. Drive-up lift is great for lowered cars. I found my exhaust shop. read more

Great experience, Dago really took his time and took care of my car. I expressed to him what my issue and concerns were with the exhaust a previous shop had done just 3 weeks prior. He did a great job addressing everything. Very communicative and kept me in the loop on what he was planning for it. What I got was a truly clean install, lots of ground clearance and great fitment on this custom build. Definitely recommend Dago for anything from basic exhaust repairs/ jobs to custom jobs. read more
