intake airbox mod, airbridge/coupler and b & b prt exhaust,x-pipe.
ls1 edit.
13 runs ..and 2 hrs later 373rwhp and 362 tq, my biggest gains were in the mid range 3000-5000rpm almost 25 hp..for street in kaliforneia , didn't think headers worth the $ and hassel
many 01's respond to the basic mods just like 02-04 's do

FLP Longtubes and X pipe Hi Flo Cats
Magna Flow Cat back
Hurricane Intake
LS1 Edit 370rwhp and 361rwtq with a rich tune adding a 125 dry shot later....
Vortex Rammer + Kooks LT headers w/ cats + Stingers w/o any tuning = 371rwhp/374rwtq on mine w/ re-ring done.
Getting tuning on 1/7/06 new numbers to come. I'm hoping for around 380 w/ a safe HPDE tune.
Honestly I don't really care about the numbers I just want the air/fuel in line and my hi-flo cats to stop throwing codes so I can pass a state inspection!
