Hey guys, im a new to these forms... so Hellooooo to all! Anyways.. I have a 05' Raptor 350... what do you guys think of the HMF slip on? I know its going to be louder then stock, but does anyone know how much louder? I like the look of the HMF, but if anyone has any other recomendations that would be great. Also, with a slip on pipe, do I have to re-jet, or just adjust the carb?
