It's who you knw, it really is. i got a cmbelt from euros £180 they wanted, my mates trade discount £60 for it

Back box (from here and p+p) cost me £30. Again with my mk3 the exhaust wasn't a straight fit luckily a mate of mine knows a man (genius, can do anything, welding, mechanics, plumbing, panel beat etc...) he turned up, cut the pipes to length, welded the pipe (my mate cut off with an angle grinder to fit round the axle) back on, cut the other pipe to length and the backbox was on. Exaust pasted each end together, an exhaust bracket added for a bit of security and bom! he did all that in 30min, mans a genius
