Right exhaust pipe
Right-hand exhaust header pipe for 1969-1970 model catalog listings, also known by its earlier alias E9663.
70-9663 is the right-hand exhaust pipe, the header that runs off the right exhaust port down to the muffler. It shows up in the exhaust system figures under both the engine fittings and motor fittings headings, and the catalog record ties it to the 1969-1970 model years. You may also see it listed under its older alias, E9663, which is the same physical pipe under the pre-1970s numbering.

This is a right-side-specific part, so don't try to swap it with the left pipe - exhaust headers on these twins are made to match the port they bolt to and the routing on that side of the frame. If you're replacing pipes on a bike from this era, check the header against your existing one for the flange style and any bracket mounts before you order.
Give us a call if you're not sure this is the correct pipe for your particular machine - the catalog entry we have is brief and we want to get you the right side and the right fit before it ships.
