Attention: TDR Forum Junkies 
Thanks for the comments folks!
I know I'm just a bit 'peculiar' when it comes to stuff like this.
All my family have a running joke that if you want something researched to death, give it to me.
Four inch to five is surely adequate. Heck, from what I've read, we don't even NEED a four inch exhaust (not sure I can fully believe that, though). It just would be neat to have a five inch back from the turbo; don't ask me why! Like I said, I'm sort of 'peculiar' that way.
