Any one any ideas where to get one from? Tried GSF, ECP doesnt seem to stock it, all the kwik-fit type of places only list 3 peice systems and I dont really want to pay £350 to replace the whole system (even though it may be cheaper in the long run)
Don't really want to call BMW because Im too scared of the price!!
Also would my car have a Cat? (December 1989 325i Touring)
Any help will be welcomed!!

Thanks
Mark
