Other than the cheap clamps (broke two on install) this is a nice system. Ended up welding it together. Love the sound...not too loud but very deep.

This took roughly an hour for installation and was pretty easy. A big change in both exhaust note and throttle response. The truck roars to life now, but maintains a gentle purr at idle and cruising. Combined with the Airaid CAI this dynamic duo lowered RPMs, increased MPGs (avg +1 MPG so far), and seriously increased driving excitement.
