I have sold and installed these mufflers for about a year now. The reaction I get from my customers is very good. After being in the exhaust business for 20 years I can honestly say I have not seen a better constructed muffler not made of stainless.
2 1/2 inch and smaller sizes sound very similar to Walkers Dynomax but flow is considerably better due to true straight through design. The 3 inch version is very loud by my description. I have a 3 inch in, dual 2 1/2 out on my 94 extended cab that I like a lot but I have a dual 2 1/2 in and out on my 99 Suburban with dual pipes out behind the right rear wheel and I LOVE it!
