shorter and more open is always more hp unless its too short.. then you burn your motor up.
but... you're NOT going to notice the extra horses from just an exhaust build....
yippee.. 5 hp at the sprocket... cool... 0.05 hp at the ground.... cooooool... may even stand the bike on it's back tire with that extra power...
there are better things you can do to get power... exhaust is just the first step..
the second step is to buy a busa
