nope
what else did you have on other than ottp stage 1?
Lol. I don't trust my butt dyno. It is always very sensitive after a resent install. And from the tone of this thread is seems like some people's butt dyno is telling them they lost hp.
I understand what you saying. But Dyno numbers are important when measure the differences between setups.
I dyno'd 256hp 238tq with my OTTP Stage 1 kit. Overall the number is not very important to me. BUT when I dyno test performance mods the difference in the dyno results IS important to me.
I was hoping that someone would have taken the time to determine if and what the gains are with this header. I was considering buying on in the future. I was going to get into the group buy but I have yet to see an independent dyno test of this header.

ALRIGHT, got my noodle install today... not to bad specially with my fancy double flex ratchet wrench :P but i had this horrible exhaust leak after i was done... found out it was the header to downpipe gasket, (yes it was tightened!!!) and i blew a good hole right in the sucker right next to where the O2 sensor is... so kinda S.O.L. i put my stock metal gasket back in and it doesn't leak quite as bad but it still definately leaks in the exactly same spot... anyone else have this problem? i'm really hoping my mating surface isn't warpaged right there...

with the supplied gasket after i blew i'd hear almost a whistling noise when accelerating and now with the metal one it is more of a chirping noise... but only under acceleration

well I was unable to get it on today. But will try for sure this week. I'm not liking what people are saying so far from results. Would it be better to use OEM gaskets?

yeah same here but i only here it with windows up and under acceleration. I might buy a new metal gasket from the dealer and see how that works out.

if it gets faster as you accelerate, like its in sync with your rpms, its valve chatter. completely normal. every gasoline motor has it, just our stock header dampened the noise. mine has a leak to, the gasket from downpipe to resonator is junk. new one should be here tomorrow.
