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 gives the v6 a nice rumble and adds horsepower as proven by Camaro Performers magazine on their project Victor Six.

I am totally pleased with the flowmaster system I insalled on my 1999 Pontiac Firebird it sounds great and I also before had the cat.. changed so all new pipes are on the car... It is a v-6 3.8 liter but sounds like a v-8.. If you want better sound and performance do it all.. and you won't be sorry........ Thank you, Roderick Bushey Tulsa, Oklahoma

In a whole i think its a good system, but my complaint was that it wasnt as loud as i thoguht it would be, and one of the clamps was to big for the pipe so I have a slight exhaust leak.
