Khrome Werks 202711P Ripper Insert for 4.5″ Khrome Werks Harley Touring Slip-Ons
This is a piece of 2.25” straight pipe with a flange on it so you can bolt it in. It basically turns the muffler into a straight pipe. Do you want your bike to be loud? This is the insert for you. This is not a performance-enhancing insert – it is solely intended to maximize sound on the rev. Bolt-in flange. These things make even a slip-on behind a cat ROWDY!
