Exhaust pipe—R.H.
Right-hand exhaust head pipe, part of the exhaust pipes and mufflers assembly.
71-3815 is the right-hand exhaust pipe, one of a pair that route spent gases away from the cylinder head and back to the muffler. It's the pipe that bolts up on the right side of the machine, keeping the exhaust system balanced and clear of the rider's leg on that side.

This one shows up in the exhaust pipes and mufflers section of the parts books, appearing across catalog listings tied to the 1974 model year. If you're sorting through a box of used pipes trying to figure out left from right, this is your right-side part.
As with most exhaust work, check the header clamp and muffler connection at the other end before you commit to a pipe swap — fit and alignment at both ends matter more than the pipe alone.
