Why? The ends would have to be sized to fit the IC and turbo anyways.... so a larger diameter wouldn't do much. Whats wrong with the stock ones? Or are they just dirty like mine?
^ Hahaha.... very true. But on stock turbo and ic... I don't think the difference would be much. And with an aftermarket one... you should get all new pipes for it to mount up right? I don't think there are any IC's that hook up to the stock pipes?
