I have been reading about people removing one baffle and others putting on pro moto billet and stainless exhaust tips, will these tips give me any more power? make it louder? is it just a tip? and does it need or work with new or removed baffles? I could use all the extra HP i can get, and i don't mind it being a bit louder, but im planning to make it a DS i need to be fairly quiet.
