Thanks for the response people! I went for the OEM on e in the end as mine has only just given up the ghost after 11 years, cant complain with that.
Next question I have is; what on earth am I going to do with the dual exit SS system I have brought from FK? I've been advised it's for a MK3 but I cant see there being much call on the second hand market. Suppose I could upgrade the guttering....
