Absolutely stunning system: Quality, Fitment, Finish, and Sound. Easily, 2x louder than stock, lighter, and makes more pops/crackles. Butt dyno approves the 18% flow. A true mild to wild system. My only regret is not shaking the hands of the folks at Corsa and purchasing sooner.

Had to call and ask for help with a payment option, the lady I spoke to was no help and came across like she didn’t want to help. I’m a little dissatisfied with the sound quality as I expected it to be a little louder exhaust but it looks good and was pretty easy to install.
