mhr sell a replica pipe...yasuni sell low reving pipes... and guess what, so do mk...so stop trying to prove people wrong...
i have had a low revving setup for my honda scoopy...it wasnt bad,for a transportation bike, but i had a technigas pipe and it was crap... the krd pipe was slitly higher reving and was much better in top speed and low end... then i tried the a fabrizi pipe(which was high reving) and i tuned my cil to produce more rpms, plus i made up for lost low end power with my clutch and varion being lighter and tighter... it was alright...
my point is that there are much better pipes then a technigas, so dont try to tell me i am wrong...krd, mk, and or mhr is probably best...i dont think yasuni sell pipes for tgb scoots...
