you may of course ask, well, i keep getting a leak at the bracket between cat and that bit of pipe to centre box, the previous owner has abused the cat abit and the pipe isnt perfectly round as should be, so was thinking next time i get the bracket sorted instead of having that pipe and centre box, just to do away with them both and just have a pipe to back box.
and if it sounds a bit sportier then alls good

in a perfect world i probably need a new cat, but as this one is working ok, well was at last mot july 2010 seems a shame to replace it
