I have heard that PU expanding foam is almost impossible to remove from an exhaust systemTwat like that goes past us at Mach 3 on a black GSXR 600, race exhaust etc etc.... Big G wants too catch him on his Busa and rip his head off. The GSXR bod rides like a complete Knut.
I think he offends G's sensible riding style, very fast, but safe.
especially one that is more or less devoid of baffles
if they dont silence him I am nicking it, its got no alarm ( I checked)
he can have it back in weekly instalments
