As no two pipes are truly identical, I suggest you
measure the diameter of yours. Take off the muffler,
measure the size of the pipe, add about 1/64th to
it, and there you go.
If it helps, the extension I used to test with an
open exhaust was 1 and 15/16 inches. The bike will
sound and run like shit if you run an open pipe.
If you like the look of a drag pipe, but still want
the bike ridable, I suggest adding a slip in baffle
(cop fooler) from your nearest HD aftermarket shop.
Keeps just enough pressure in the system for the
bike to run at least somewhat correctly.
Good luck. Don't blow up your new toy.
