Show original supplier description

The M4 Muffler Box Eliminator Kit (YA-MBEKR606) is a performance exhaust component specifically engineered for the Yamaha YZF-R6 motorcycle. This kit serves to eliminate the stock muffler box, often referred to as a catalytic converter eliminator or Y-pipe, contributing to a more aggressive exhaust note and potentially improved exhaust flow. The M4 Muffler Box Eliminator Kit is compatible with stock mufflers as well as most aftermarket slip-on mufflers, offering flexibility for riders looking to customize their exhaust system further. This M4 exhaust component is intended for use on Yamaha YZF-R6 models manufactured between 2006 and 2020. Installation of the Muffler Box Eliminator Kit is noted as requiring specific attention. As with many performance exhaust modifications, all M4 systems are designed and intended for closed-course competition use only.
