NPP advice...

New NPP mufflers are going to cost around $1400 or more for '09's plus about $150 for one of the NPP in a box kits. You may be able to find a set of mufflers cheaper in the For Sale section here (still a few members take them off for something more radical) or quite a few members have found them on the auction site. If you want to go new, the 2 best sources are probably gmpartshouse.com or partstaxi.com, both Forum vendors.

The swap is easy... I just went to a muffler place, took 45 min, and $75. The Retro Fit control will take you an hour the first time..
