The mufflers are pretty quiet surprisingly quieter than I expected it would've been nice a little bit more rumble but that was not.

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.
