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.

Installed these on my Pontiac G8. The exterior sound is a nice rumble. not too loud, not too quiet.The interior noise "drone" is rather noticable but not too terrible and has a little vibration to it. Again, not terrible. Nothing a little sound dampener cant fix.
