I needed a dual exhaust from my headers back. The issue was the the headers dumped into the trans crossmember. Dago and Cesar did a great job of notching the crossmember and reinforcing it. They ran the exhaust to the Flowmasters with a dump in front of the rear end just like is asked them too. I would recommend Advance Muffler. read more

lt;dr - Great job and price, and the best customer service. I had dropped my BMW off at the shop for a muffler delete and told them I will come back a few hours later. But I could not pick up the car because of work, and Dago had waited even after the shop was closed and had my car parked inside of his neighbor's shop to keep it safe till I come back the next day. He was incredibly nice and understanding about the whole situation. I picked up the car the next day. The job was well done and price was very fair. Definitely, 5 star worthy location. read more

Advance Muffler - Here's a picture of the shield they fabricated along with the owner of Advance Muffler. - Auto Repair Near Me - Chino, California

I have a 96 Ford Truck. The catalytic converter was stolen. I called my mechanic and he said the part is hard to get - $2400. Ouch!!!! I started calling around. Only my mechanic and Advance Muffler asked me for either a VIN or the catalyst number. Advance muffler gave a great price. He ordered the part. He called me to come in. 2 hours later he had the converter, O2 sensor and the rear driver door working. The rear driver door wouldn't open and he said he'd look at it. It was fixed when I arrived. Great communication throughout the process. Honest. Need your car repaired. Come to Advance Muffler. They will do you right!! read more

Definitely suggest this shop. I was planning to swip my bmw 435 muffler with a m2 muffler. Before buying muffler, i went to advance muffler shop to get a qoute. Ceaser helped with this matter and afte he saw the picture of the muffler I'm planning to buy he gave me the qoute. He understood exactly what i was asking and he is a knowledgeable when is coming to exhaust. The qoute he gave me was reasonable. After I bought the exhaust, i went there in morning, he worked on my car exactly in the way i asked. It came out super clean although it was not a easy job. A lof of pipe bending, sizing and etc. I'm a super happy costomer. read more

Took my c6 in to help get rid of the drone and quiet it down a little. I believe his name was Cesar helped me out. He was also able to find some other small things rubbing on the exhaust and fixed them no problem. Charged a very fair price as well. read more

Now i see why this shop is one of the best muffler shops in Chino. Dago deleted my Vibrant Resonators on my 14' Infiniti Q60s and did an amazing job. He kept it straight with me and got the work done at a reasonable price. Very honest guy and he knows what he's doing. Unlike other Muffler Shops in the Chino/Ontario area, they will try to overcharge you like crazy and barely care about the work. My car sounds AMAZING thanks to him. If you guys want your Mufflers Done, or your Resonators done, or whatever you want done with your car. COME TO THIS PLACE. You won't regret it at all. Don't go to any other Muffler Shops in the Chino/Ontario area. read more

Dago, the owner is professional and cool, he gave me a price estimate over the phone as how I like it instead of coming in. Cesar the tech took his time to install my Magnaflow muffler and ran 2.5" piping to my liking on my Gx. Pricing is fair for the work they do. I would recommend these guys to anyone that wants a good and reliable muffler job without the sloppiness of some shops. read more

I was so bummed out that some jerks had stolen my catalytic converter and I was even more depressed when someone told me it would run me a few Thousand dollars. My regular mechanic had recommended that I go here, and Dago was so cool and very accommodating. He even went out of his way to pick me up from home and pick me up after the job was done. My driver's window was giving me problems and it would not roll back up. Dago went out of his way to order the part I needed and gave me a very fair price. Thank you Dago and Caesar! Will definitely be coming back! read more

I had an exhaust leak that I wanted checked out but I was in a hurry so I was willing to bring it back the next day if it couldn't be fixed in time.

I went to this place because it was marked 5 stars and once I got there I spoke with Dago who installed my 2 catalytic converters on my 07 Yukon. He was thorough and very helpful. The service installation was fast. The prices are very reasonable and the service u get is 5 stars. I went to get a smog check and it failed, however it was not Dago's fault, the technician at the smog company entered wrong information. I called Dago and explained situation and he took the liberty to call the Smog company and stated to them they made the mistake. Upon further review the Smog company realized they were at fault and re-smogged my vehicle and it PASSED. If Dago would not have taken the liberty to call and straightened it out, I would off been going back and forth with the smog company. Thank you Dago for going above and beyond. Highly recommend this shop! read more
