I currently have a V3 HO vortech blower @ 11lbs of boost, and getting the Brenspeed Detroit Rocker cams installed in July, as well as a dyno tune. Currently I have BBK Equal Length Tuned Headers and a pypes off-road x-pipe w/ a set of custom Stainless steel mufflers out back. Should I spend the $ and get the Pypes longtubes and offroad x-pipe and get rid of my current shorties and x-pipe? Is there going to be a huge difference changing to the longtubes? I do have a blower and cams, so I'm being told I could gain 30+ RWHP changing to longtubes with my setup.. IS THAT TRUE?!?! Anyone w/ f/i switched from shorties to longtubes?!?!
