thought i'd ask in here as opposed to starting a new thread.

Midori has some 90mm front pipes now... i've got 80mm ones and not 100% on what mm the catback is... given the increased kw #'s we're putting out with E85 etc... would there be much gain in going to some 90mm front pipes? or is it waste of time unless the rest of the system is 90mm??
