In an ideal world, I'd love a P/E but not sure I can justify that not insignificant sum of money!

I'm sure someone will correct me if I'm wrong, but as far as I know, the back box simply serves the purpose of noise reduction and has no effect on MOT emmisions. Thus the removal of it should hopefully provide me with a sportier sound but without the expense of a full system.
