Jeff was great would recommend to others looking for muffler work

Jeff is awesome 🙂!

Great experience, Good price and Great service. Needed a trailer hitch installed with some welding, a tricky installation and they did more then I expected. Welcome relief from past dealings with other shops where the price just keeps creeping up. Price quoted was the price paid. Jeff runs a honest shop and delivers top notch quality service.Highly recommended!

Great service & prices + cutom work done.

Been getting work done by Jeff for over 12 years. Whatever information this guy gives you regarding your exhaust system, you can take it to the bank. Ive never found any auto service technician more skilled or knowledgeable in their field. Jeff does it right the first time and his prices are reasonable. -R. Mirabella (Simi Valley)

Very helpful and knowledgeable. The muffler I needed was in stock and he squeezed me in same day. I will be returning for anything exhaust related. Highly recommended

Took my firebird In for a performance exhaust upgrade.Jeff was direct, to the point and got it doneThe bird is flying and roaring.Very happy with the results.

Jeff was awesome. I had a big hole in my muffler and he has the right part ready and installed in about an hour. Really happy with his work.

Cant say enough good about how Jeff treated my wife and I today. Resolved our muffler problem in less than two hours and saved us over $2000 from our estimate from the local Toyota dealer. Honest, fast, and reasonable. Highly recommended!

Excellent. Replaced a muffler while I waited. Old school service and quality!

FIRST CLASS CRAFTSMANSHIP!!! I cannot say enough about the professional and quick service at this business..had them do duals for my 69 chevelle in 1979,and came back in 2014 to do the same in a 77 chevy 4x4 and both times got some of the most beautiful exhaust work Ive seen anywhere!! HIGHLY recommend.Youll thank me later...Mark.

After the muffler I purchased from Midas failed within three years because of cheap parts and shoddy workmanship Championship Muffler sold me a quality muffler and installed it properly, with solid workmanship, at a reasonable price. If youre looking to get the job done right the first time this is definitely the place to go.

Great guy

Fixed me up for $75.00, and believe me I needed some fixing.
