Left exhaust pipe
Left-hand exhaust head pipe, catalog number 70-4884, supersedes 70-4886.
70-4884 is the left-hand exhaust pipe, cataloged under EXHAUST PIPES AND MUFFLERS (U.S.A.) for 1966. It carries the earlier alias E4884 in older parts books, and this number itself supersedes the earlier factory pipe 70-4886, so if your book or an old pipe shows that number, it's the same part under a prior identity.

This is the pipe that runs off the left exhaust port back toward the muffler, routing spent gases away from the cylinder head. On these high-pipe setups the pipe is a distinct left/right pair rather than an interchangeable item, so make sure you're ordering the correct side for your bike.
