Yeah of course! For one thing the stock one ways about 5 times more than the sport ones so that will slow it down alone, plus it will add on extra HP, whilst the stock one derestricted will simply put the HP up to what it should be. If youre getting one go for a ZX or an S, they are both nice pipes and they add on 1HP alone. The giannelli NRX also works, but it is not proved that it increases HP.
