Awesome!

Reviewed By Sam B (albany, IN) Reviewed for a 2003 Chevy C/K 3500 —3/17/2017 1:01 PM

I have a lb7 duramax with a 4 to 5 inch straight pipe. It was ungodly loud especially on the interstate. This muffler doesn't make to much difference at low rpm (which it still quiets it down a bit) but it makes a world of difference once you give it throttle. Especially at 2k rpm when it starts to drone out. The truck still sounds awesome but not nearly as loud! It was exactly what I wanted!!
