RE: headers question (not a typical one)
on the dyno, stock i was 255 hp, after LT's , o/r x pipe, boomtubes, JLT and tune i'm now at 301 hp. thats 46 hp gain for you slow peeps. so i estimate 25 for the JLT/tuneand about 20 for the LT's and o/r x pipe, give or take a few hp. so thats real numbers, sure they'll get more w/ FI, and i'm putting that in later in the week. but my LT's are already in so less work to do now. in the end it doesnt matter LT's first or SC first, just a matter of preference.

I disagree completely. The stock manifolds are just about the only restriction in the stock exhaust. LT Headers are good for 10-15. High flow cats over stocks are worth nothing, the stock cats flow very well. If you went to O/R h maybe 2-3 hp, O/R X maybe 5.

Shorty's aren't really worth it, you're basically replacing the stock headers with the same sized part but with a different coating. Long-tubes add more power and better sound and would probably be worth it, but they're a bitch to put in. Someone correct me if I'm wrong, but that's how I've understood it.
