As above Iv just fitted a full 3in stainless system so my cobra back box is up for grabs and it sounds brilliant it cost roughly £180 but I only want £50 but also it can come with standard down pipe and middle section both cats are ok £80 for all of it but it does need a clean 

location is Gravesend in Kent 

Hello mate, am interested 👍

whats postage on this back box only, what size is the inlet/bore

I think it's 2 1/2 in with a 4in tip but sounds really good but I'm not sure on postage I thought no I could get a courier for about £12 

that don't sound too bad, can you just check the bore internal size for me mate

Which bit is that coz all I know is it's 2 1/2in in diameter 

This bit mate, needs to be at least 2.5 internal, the one in the pics is 2 and a quarter 

I will check in a bit and let you know 

:)

Any joy mate
