Looks good and wasn't too pricey and great pick up, but a little too loud in my opinion.

Sounds like a stock LS1. Great exhaust system! For it to be installed the right way you need to add an extra hanger or the right side hangs too low. Awesome system! Added a significant amount of Horsepower! Throaty sound! Worth the money!

This exhaust is just what I was looking for. It really opened up the car ALOT. It gives a nice smooth rubble while accelerating but when you get to cruising speed you can barely hear a drone inside the cab. Great hp increase, too early to tell about mpg. Def best bang for your buck.
