Great sound, and cheaper than competitors that I looked at.

I installed the exhaust last weekend and its great. Sounds good, not too loud inside and a 2-3 mpg increase in mileage when coupled with my K&N 63 CAI. I highly recommend this product.

I installed the Cat Back system - American Thunder a few weeks back. I was fun scaring the neighbors with the sound of the 5.7 liter but the drone between 1700 - 2000 rpms finally got to me. The resonator killed the drone and muted the cat back to some degree. Although Auto Anything claimed this to be a "button up" installation, it really isn't. You'll need to cut into the existing system and I recommend having it welded by a reputable shop. Nice mellow rumble now.
