Ok, I see where you're going with this Kremit. You win, on OUR CARS it can't get too bad with length. I was on a different page. I was talking overall concept. Hell, maybe I'll buy one later when they come out with the CF pipe, but until then, no use in sticking a long aluminum pipe underneath the hood for it to heat up. I can't believe I'm admitting a loss to Kremit...oh well, arguing is fun and somebody has to lose. I'll get you someday. Somebody should probably get one though to test it out. One thing that is not for certain though is your comment that a 130hp engine will see 11whp...there are many variables that come into play. maybe you should say, there are significant gains to be had.
