Schumacher header to TTI's

Thinking about go from Schumacher headers to TTI headers. Anyone else do this and see a big differance at the track. My last run at the track was a 11.93@ 113 MPH with some wheel spin a little past the starting line. I know TTI's will flow better, but I also like room around the motor.

This is a question I really want to know the answer to also. I'm going with Schumachers on my 440 Duster mainly because I want to keep my power steering. My combo should run mid 11s and I'm figuring the engine should make around 525 HP. So far I have not seen any direct comparisons on a dyno but , I wish someone would do it so we can know for sure how much the Schumachers cost in power. My guess is on a motor like mine the loss will be about 30 HP, but that is just that, a guess. I'll also say this; if I ever do upgrade to the TTIs and the gain is small, I'll sell the TTIs and go back to the Schumachers.
