Title: HM300 exhaust question
Post by: burchy75 on July 04, 2017, 07:26:43 PM

Quick newbie question about the original HM300 exhausts for the K0 and K1 CB750.  Did they have the paragraph etched on them at the rear of the muffler itself.  I have a set of HM300 exhausts here that are surplus to requirements for my build and I wanted to know whether they were original or not as I heard that the originals didn't have the paragraph on them at all.  Any help would be appreciated.

I'm sure someone will correct me if im wrong
But I believe the blurb had to be put on after a certain date to comply with some new law
Doesn't men they are not original just a later set of manufactured pipes

As fa as I know the "HM300" stamp is different too on those with text.

I dont know when those with text came.
