2005 Pontiac GTO 6 Speed

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.

Solid Muffler. Good Sound!

Reviewed By Nicholas O (Algonquin, IL) Reviewed for a 2000 Ford Ranger —4/19/2017 3:52 PM

Solid construction and good fit because.....its universal! Most of my exhaust is custom since the original rotted out so it sits only a foot off the cat pipe and turned down....if a good rumble is what your after this muffler will suffice but your scenario may differ.
