RWHP Estimate

Not to be a negative nellie, but there is no way just an x-pipe back is going to give 35 hp. Lucky if you see 12 to 15. Heck on a stock GT with a full exhaust, headers all the way back 35 hp, is really pushing it in my humble opinion. Only way to tell is take it to the track before the upgrade and then after. If you've got more mph after then you got more hp out of it, just use the calculator then.

no one said 35hp from the x-pipe

but 35 fwhp from all his mods
is possible


I have seen a bone stock 01GT pick up 12hp and 10 tq from just dyno tuning with a sct chip and I have seen a mach 1 pick up 15hp and 12 tq from just dyno tuning and that was to the wheels

so the gains would be closer to 15hp to the flywheel (GT)
and over 20 (mach)
