i dont know why there is such a fight over this shit everyone should just build bikes the way they want them, and go have fun....keyboard racing solves nothing and is rather stupid, by the way ive never run either of these pipes....from reading most of this its like a "whos dick is bigger competition" just go have fun and ride some fast shit, get your adrenaline pumping and dont worry about 2 HP ur ass wont feel it anyways
