Hmm. Mystery pipes. The KH pipes are definitely larger radius or "taller" Than K because of taller cylinders by 3/4". I can't think of any application for even taller ones except maybe a custom stroker. Interesting.

on the front pipe where it comes out of the head about 3 inches down the pipe it is indented a little to clear the frame tube looks perfect for fitment ???

Sounds like XL early pipes?
