Guys stayed until l got there after work, changed my Catalytic Converter, my O2 Sensors and give me a Flowmaster muffler for my Jeep Cherokee XJ .. Did an excellent Job! Runs way better and sounds even better!

Really good and honest service! He wouldnt even let me pay until after a test drive. Highly recommend this man, he will shoot you straight! Saved my bacon on some bad catalytic converters.

Stole my parts, didnt do what I asked, overcharged, wouldnt let me walk in horrible customer service. Didnt know what they were talking about over the phone

Mr. Felix was a really nice man we didn’t have an appointment but he worked us right in & got us taken care of I was pleased with his work!

Great and fast service vehicle sounds wonderful runs great

My experience was great! We had someone tell us that our Muffler was cracked and about to fall off.. So I took it in and he said it was just the tailpipe that was about to fall off. So he fixed it in about 5 minutes for free. I would definitely recommend this place. He was extremely nice and very quick.

Great service Dropped my truck off. And recieved a call a hour later, saying all was done. Sounds great, welds look great. All in all, great transaction.

The only muffler shop Ill go to in the area. Excellent work at a fair price. Highly recommend!

Great service! Felix, the owner, is a down-to-earth guy and super friendly. He installed a muffler for me that I brought him. Very quick as well. Would definitely recommend!

I went in to have a flowmaster muffler Installed on my truck. Felix was very friendly and gave me a really good price! I was referred to him by the person I purchased the muffler from. I would recommend him to anyone who values good work and fair prices. Ill be coming back when its time to upgrade my vehicle again!

Im so glad I took my Heavy Duty truck there. The owner did excellent work and charged a very fare price. Its not easy to find an honest auto repair shop but this guy did honest work at a fair price. I highly recommend.

Went here when our truck developed a loud rattling noise in the muffler. Were from out of state and pulling a camper. The owner, Felix, was very nice and determined the heat shield on the muffler was rattling. He removed it and replaced a couple of rubber rings. When we went to pick up the truck he didnt charge us anything for the repair. I cant express how relieved and grateful I am to have found this place. Felix is an outstanding and honest businessman! Highly recommend!

Owner is awesome. My pipe broke between muffler and converter. He could have said I need to replace both but told me they were good and just needed to replace pipe. Honest and fast.

I own a shop, but dont do exhahust. I take all my work to felix for years. He has great service and best prices.

He did a great job. Did exactly what was asked. Very fast and no burns or damages. The owner is very friendly and very very helpful!

When you need new mufflers, come see M &B Muffler, they do a excellent job

I scheduled an appointment and got my vehicle back same day at the quoted price.

I wanted a low growl to my silverado and Felix did exactly that! He put it on in a very timely manner and his prices are very reasonable I would recommend this shop highly, if I ever need an exhaust for another vehicle I know exactly where I’m going

Nice owner, great service! Ordered a carport and really trust itll be great... update~ it is!!
