I was looking at full exhausts for my busa and i realized that with a full system akra or yoshi exhaust, pc3usb and a dyno tune it would all come out to over 2 grand.Other than the cosmetic and sound effects is it really worthwhile in terms of performance after spending that much money? Ive heard that the hp increase is around 10-15 after its all said and done.
