RPi will have a 645i/650i exhaust system available soon that won't lose power.

I am going with RPI because of these reasons:


1) Price was decent
2) Sound was awesome
3) HP gain
4) Tips looked badass

Oh, bummer man. Sorry to hear it. That's the worst feeling in the world, spending all of this time & money then losing power.
