RE: How Much HP are We Really Getting from Exhaust Systems?

the dyno quotes from cervini, about thier side exhaust kit was 9 RWHP and 13 RWTQ, so about the same as pulleys, no I did feel the differance but it could all be in my head.

Please don't misunderstand. I'm not saying that I don't believe you, but I don't [&:]

JBA's website says 28RWHP peak gain with it's LT's, X-pipe, and no cats.

SLP says "up to" 30 HP RWHP with LT's Xpipe and no cats.

I've installed the latter above. Haven't done anything else yet (though I have the parts, I just want to drive off my 87 octane before installing it) maybe I should dyno my car before I do?

If everyone pitches in a couple of bucks for it, I'd be more than happy to dyno it before the Tune, CAI, and U'D's are installed . [8D]

PS: I have a baseline for my car already too.

+1, I would like to see what my car is pulling with my JLT II CAI with XCal II and Evolution Performance tune, with Borla CatBacks, and Hooker X-Pipe. I hope that is at least fourty horses right there.
