Can you hear me roar?
I'm very impressed with this American Thunder system. I listened to a lot of exhaust systems online and how can you go wrong with a proven system like Flowmaster American Thunder? I did the install completely alone but of course it would have been easier with another helper. I took my time and made sure everything fit right and was positioned right and the way I wanted it before tightening every clamp down. Took my time over the course of an afternoon and when I fired her up....WOW!! Love it!

Happy with my order and purchase. I was on the fence between Stainless works and another brand, but these headers are high quality. In relation to power, it is a very noticeable gain and I have not tuned my car yet (it feels like I am on Track mode at the default setting). The sound is great, nice rumble, not loud at all until I go WOT lol. On another note I did notice that my gas mileage improved by up to 3mpg. So I am very pleased with my Stainless works long tube and i got high flow mid pipes
