Well I have a GPR that's loud and functional.
Not pretty but nothing that a rattle can of satin black wouldn't sort.
Unlike most of the ones apart from Akra/Arrow this has the proper link pipe, valve cover, etc. The baffle however has left the building.(well it may well be in the bottom of a box after 2 house moves but `I don't know which box.)
I'll get a pic after for you when I pull the mower out.
