"Some modifications may be necessary" my @ss!! But with some patience and a lot of work the new exhaust is on. 1 7/8" Hooker SuperComp Adjustable length headers with 3 1/2" collectors. Right into 3 1/2" dumps, then reduced to 2 1/2" aluminized pipe into dual FlowMasters. Sounds nice, not too obnoxious but definitely mean sounding.

 

why did you feel it nessasary to go with 1 7/8" headers and then only go with 2 1/2"? Seems like waaaaay overkill unless you spinning high RPMs and making huge amounts of power.

 

Not huge RPMs, but definitely huge power. The dumps will be open at the track so I can take advantage of the free flowing headers. I went 2 1/2" for two reasons. 1) I already had the Flowmaster 2 1/2" mufflers and 2) it gives better ground clearance. Down the road I'll probably go with the full 3 1/2" duals. It ran 12.20 on 9.5 psi boost. The new cog setup should be running 16 psi boost. So the big headers are gonna definitely be necessary.
