BTW, there's a rumor going around that the Fister/Gundo mod might reduce slightly hp at lower rpm's because of the reduction in backpressure. Did you notice this?

Might be a little late to respond to this, but no, i havent felt a loss of HP. Also, I think it is hard to feel a 1-5 HP loss/gain, anything above 10 is maybe a little more noticeable? The exhaust is solid though and highly recommend.
