The Yoshimura AT2 Street Slip-On Exhaust is a bolt-on muffler built around a stainless steel canister with a matte carbon fiber end cap, mounting to the stock header with no ECU remapping required.
AT2 stands for Alpha Taper 2, Yoshimura's current-generation canister and the successor to the Alpha-T. The Street Series version is the one to have on a road bike: it is a slip-on/bolt-on application that does not require tampering with the vehicle's emissions control system, and the faceted end cap assembly gives it the distinctive profile the range is known for.
Installation takes minutes against the factory header, and no fuelling changes are needed. The canister accepts Yoshimura's optional sound inserts for riders who want to bring the volume back down.
The specification above is confirmed, but the motorcycle application for this part number is still being verified — Yoshimura builds the AT2 Street slip-on for a wide range of bikes. Contact us with your make, model and year and we will confirm fitment before you order.
