From what I have learned, the difference between the long tube race header and the shorty header is minimal. Minimal as in 1-2 hp gains with the long tube. But the noise of the long tube header is deafening. I am warning you now, don't get the race header. An RT cat and the shorty with a 2.5" flex pipe will cost you, but the ability to drive your car hard and still be somewhat quiet you will thank me for later. Especially at highway speeds.
