just bought a mk4 2.0l 8v gti on a xreg with 40,000 on the clock and got about a £1000 to spend on mods. installed a decent sony head unit for £150 the other week then put in a k+n pannel filter for another £50 leavin me £800. the next step is hopefully to find a gti spoiler from somwhere and then do a few performance mods. not sure on wot to do tho. was looking into a cat back system from milltek but you have to fanny around changing the rear valance for a 4motion style rear valance and thought the extra money and effort to do this wasnt really worth it. somone suggested getting a sport cat for it but not sure they do one for a mk4 2.0 8v and if they do wot sort of powergain i would get just from a sport cat? any suggestions very welcome as im a little stuck on wot to do?
