Just a quick question I hope, do all Prodrive back boxes have the same diameter tail pipe. Recently fitted one back on my UK300 along with a 2.5" stainless centre section but I am not sure if the tail pipe on this Backbox is a big as one I had previously.

Any ideas or thoughts guys?

Thanks in Advance

 

I think there could be a few different tailpipe designs over the yrs, if only very subtle changes. My hawk has a Prodrive branded backbox on now, I also had one that came with my blob and that did seem smaller.
