Advertising this on behalf of a friend who runs a garage, he took it off a 2007 E86 coupe before fitting an aftermarket exhaust. It’s in good condition and is situated in Glasgow.
He’s confirmed to me that it’s in full working order, obviously slightly aged but with no damage to it and all brackets present. He’s happy to clean it up and package it if you could arrange your own courier. Let me know if that’s of any interest to you.
