I have two muffler bodies but no end caps that I want gone. They are the same as used here http://mastslav.weebly.com/ and if the plan Corrimal MS used is followed the noise reduction is down to about 72db for a CV Max. This would only be suitable for anyone who can pick them up as to freight them would be exhorbitant. Either they go to good homes or to the tip and the price is right, free. PM me if interested, I am in Helensburgh near Wollongong. Anyone who knows my phone number can ring of course.
