Fredo, it sounds great. Reminds me a bit of my own exhaust.

Re: Wow.... Headers are in.

On the 5.7 I've been told by a few people to expect around 40. The torque feels insane along with the throttle response. No loss of low end and a huge gain throughout the whole powerband. My CMR tune from Tom @ MHP really helps make this beast pull and shift insane.
