the 70mm dose make more power than the 63mm Headerback I had on my car before, but I was expecting more I guess....... On a side note. the T1r came in without any gaskets, so i had to make due with what I had, the flange at the rear(axleback) has a HUGE leak.... Im going to try and find a gasket that works today at lunch.
Im not sure if that was hurting me or not but the car is RFL right now. and nasty sounding.
here are the numbers
63MM Headerback, T1r 63mm Testpipe+ Spugen Single Ti V2
VS
70MM Headerback T1R 70.
Peak It made 4HP and 2-3-4 HP everywhere else, lost about 2hp at 4200RPMs but it makes up for it everywhere else.
here is the Sheet. Possibly re-dyno this afternoon if I get the flange to seal!
^^^The exhaust leak will defenately rob power from you...they tend to cause all sorts of turbulence in the exhaust flow. You want that flow as linear as possible.

you'll probably get another 2-3 back.
