Took it to the local muffler shop to get it welded on, sounds great.

These Super 40's really woke the car up. Very noticeable gain in acceleration. I also had my muffler shop install an X-Pipe and wow did this pairing wake this GTO up. Spent half of what a cat back system would of cost.

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!!
