Oh yeah, forgot to mention, I also put a Pete's cover on the 6637, which adds $25 to bring the total up to $75 for the whole intake conversion:

The 4" exhaust is a bit of a bear to get in - not a lot of clearance on the Excursion... probably similar for the trucks. But worth the effort - I love the sound - mean and throaty like a V8 should sound and the sweetest whistle on top of it. Some people straight-pipe it with no muffler; but I think that might just be too punishing. The kit I got (
www.diamondeyeperformance.com) has a straight-though muffler with rifling; so it actually helps keep the cab drone down and speed the exhaust out a bit more.
Ah... truck toys. What could be better?
