Boy Bill, you sure beat me to that one.
Now, of course the 450 Scrambler exhaust will fit but not too easy to find. Know anyone who might be able to fab up an exhaust?
Just happened to be here when he posted.
Not a lot of interchangeability with the exhausts on old Hondas (uh, like ZERO). 350 to 350, 450 to 450, 175 to 175, in terms of CL/CB - that's about it.
Any of the old CL exhausts are very hard to find in good shape.
Actually ANY old Honda exhausts are golden.
