The Bassani 4" Slip-On Mufflers use a perforated 2" core and removable baffles for an aggressive sound in a 4" body.
These are the 4" slip-ons, a step down in housing size from the 4-1/2" version but built around the same idea: an aggressive note for a rider who wants one. The perforated 2" core is what shapes that sound, and the removable baffles let it be adjusted. A complete hardware kit is included for installation.
How the 4" Mufflers Are Built
The 4" bodies carry a perforated 2" core for aggressive sound and performance, with removable baffles. Black billet end caps have flutes. A hardware kit is included for installation. Made in the USA.

Before You Order
These are slip-on mufflers for existing headpipes rather than a complete system. ⚠️ VERIFY your headpipe compatibility before ordering.
⚠️ VERIFY street legality and emissions compliance for your state and model year before purchase. Most aftermarket performance exhaust systems are intended for closed course competition use and are not certified for street use in all jurisdictions. Plan on retuning the bike after installation.
