This muffler sounds amazing I love the deep rumble it gives at both low and high rpms

i bought this to replace the choking CAT on my pontiac grand am, and first time i hit the road after installation i noticed a nice lil boost of low end torque, sounds nice too. was hoping to install it myself but the bolts were rusted and needed a gasket for both ends of the pipe so not exactly just take it out of the box, take the old 1 off, put the new 1 on, but maybe it's not the same for every car.

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.
