CONFIGURATION
The Akrapovic Slip-On system for the Yamaha comes from our offroad MX / Enduro group, as can be seen from its design. It is composed of a conical stainless steel link pipe which is welded to the muffler. It is attached to the stock header assembly with a sleeve joint secured with a metal clamp. The inlet cap is made of stainless steel due to the connection to the link pipe, as is the outlet cap. The inner perforation is also made of stainless steel. The muffler outer sleeve is made of titanium. The system is attached to the motorcycle with an Akrapovic carbon-fiber clamp. The system includes a noise damper for the European market, and an approved spark arrester for the US market, which is indicated on the muffler with a laser engraving.
