Just spotted this on the bay

Might be of some use to someone.

 

Quite expensive though, although it's a Revolution backbox and looks in good nick £140 is a bit optimistic I think, I've bought a complete Revolution 3" system inc downpipe for less than that!

I do prefer that backbox to the oval one that's fitted to my exhaust though
