Unfortunately I don't have a sound clip, but I had them on my car and was very pleased. Sounds similar to Flowmasters (but a little different and maybe a little more ?quite?)or a louder version of the stock exhaust. Too bad you don't live near Columbus, I have a cat back I would let go cheap. They would not fit with the MM heavy duty torque arm/rear suspension.Mus408 said:Anyone using the MRT Max Thunder cat back with X-pipe,with or without cats.
Wanted to get an idea of the sound.
Their website only has a clip of a Mach 1 with H-pipe.
