The V&H slip ons are several inches shorter than the stock cans and the satin finish to them matches the rest of the stock exhaust system. Pretty much the gold standard for slip ons for the Muscle. Had them on mine. Gloriously loud. You will definitely need some kind of Power Commander or something along those lines though. Even stock the Muscle runs kinda lean. With those slip ons, it will be super lean. Noticeable surging below 4000rpm and a massive amount of popping on deceleration.
