The Yoshimura AT2 Street Slip-On is a bolt-on muffler with a stainless steel canister, a stainless outer sleeve and a carbon fiber end cap.
AT2 is the second-generation Alpha Taper design, and the taper is not styling. A canister that narrows along its length holds the volume a street-legal noise level requires without the parallel-sided bulk that usually comes with it, which is why the AT2 sits closer to the bodywork than the muffler it replaces.
As a slip-on it keeps the factory header, so fitting is a clamp, a hanger bolt and a spring — no remap, no fuelling changes, no compromise to how the bike starts and idles.
Confirm fitment before ordering. This listing arrived from the distributor feed without a verified application, and we will not publish a make, model and year range we cannot stand behind. Check part number 960-1123 against Yoshimura's application chart, or contact us and we will confirm it for your bike. Check your local sound and emissions requirements before fitting.
