Thanks all:
1/. I will look into the mirror (pardon the pun) - from Librands and other places.
2/. I will probably go for a sports exhaust, however, I might just try smaller silencer boxes under the running boards, first.
3/. Yes I do think (after looking into it) that swapping out the front bumper will be expensive...but hey we are only here once (man maths)
Regards Mark
