I installed these today on my 2001.5 HO 4x4 6sp. The Air Raid intake took about an hour and I thought it was straight forward. The locking clamp design could be better but its on. I also drained every hole front to back and put Royal Purple Syntheti in. While I was doing it I installed a Mag Differental cover on the back differental. It also was easy. The 4" turbo back exhaust was not easy.......I ended up using a saw-zaw to cut most of the old exhaust and old hangers off and the turbo pipe of course was stuck. Those bolts would not break free. Ended up using Liquid wrench on them and a propane torch to heat them up. Then while hot used a 1/2 in breaker bar to bust them loose. Once off the new stystem went on fast except the turbo down pipe, could not get outside bolt started....just not enough room. Finally after pieing together a ouple of extensions with u-joint sockets I got it started. Clamped everything down and fire it up. Now I have an annoying metalic vibration noise that goes away if I put my foot on the rear tail pipe. Figure I will just use some sort of metal strap to put pressure on it so it goes away. Yesterday also I had 6 new 235/85/16 Uniroyal load range E m&s tires put on and 2 new everstart 875cca batteries installed.

I can tell a difference in power and response and thats what i wanted. I also Bought some other parts (SB 550 Ofe clutch, rough country dual front shock kit, Luke's Kit for the track bar, BD lift pump, New front heavy duty brake rotors and pads) I get to those next week. I know I need gauges and they are next. Then a box of some sort but i want one that is brain dead easy to mess with and simple to install. Just trying to get a great tow vehical.
