I've seen at least 1 website claiming improved hp with unequal length headers. Something about the pressure pulse. I have a hard time believing them since it seems to me the unequalness would need to change with RPM. Personally, I'd stick with tuned (equal length) headers. I guess that might be considered old-school now. I think they sound better too. I do like the idea of the resonated ART test pipes though. Never heard them, never tried them, but they look interesting.
