   so i would have to change the whole exhaust rather than just the mani?

   Well I wouldnt have thought the smaller bore would be good for top end power..

   you could get away with it but probably restrict the power slightly,, tbh mate if you've already got a performance backbox then just by a vts centre pipe , they like 25 quid brandnew

   if you have a performance backbox then there usually over the standard bore so it won't make any difference, if you have a VTS centre pipe then it'll be the same bore from the CAT back unless you decat etc, to the backbox where the bore will change if you have a bigger bore performance backbox
