Yoshimura RS-5 Street Stainless Slip-On Exhaust with Carbon Fiber Muffler | Honda CBR600RR 2007-2008

The Yoshimura RS-5 Street Slip-On Exhaust is an undertail bolt-on muffler for the 2007-2008 Honda CBR600RR, built with a carbon fiber muffler sleeve, a carbon fiber cone end cap and a stainless steel link mid-pipe, running a high-flow straight baffle with a removable low-volume insert.

This is the carbon-sleeved version for the 07-08 chassis, and it will not fit the 2009 and later CBR600RR, which moved away from the undertail layout. On a bike carrying its muffler high and far back, the weight saved by a carbon sleeve improves direction changes as much as it lowers the number on the scales.

The trapezoidal profile is what lets the RS-5 work in the undertail position: the flat-sided sleeve packs far more sound-absorbing material into that tight space than a round canister could, allowing the straight-through baffle to flow properly.
