It was easy to install and had good instructions. Sounds great with a little grawl in it. Not overbearing at cruising speeds.

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.
