Emgo | 3-Piece Exhaust Reducer Bushing Set 44.5-38.2mm

If your 1-3/4 inch (44.5mm) ID silencer rattles or won't seat properly on a smaller header pipe, this reducer bushing set closes the gap for a tight, secure fit. The set is also known as an exhaust adapter sleeve or reducer bush kit, and lets you step a 44.5mm silencer inlet down to match slimmer exhaust pipe diameters without welding or custom fabrication. It's a simple, affordable fix for anyone swapping silencers between bikes with different header sizes.
