Full turbo back exhaust is the way to go. Speak to Nick at R-tech he would be able to sort you out with one - he's based in Hinkley, Leicestershire. heard nothing but good things about him, he would be able to give you advice. and if you are after performance, definately get a remap after the exhaust unless you have plans to mod further - you have the KO3 turbo rather than the later KO3s, so you could expect to see power figures of around the 190bhp mark, about a 40bhp increase.
Use the search facility, i'm pretty sure there have been loads of threads on the exhaust debate.
Anni - Anniversay golf - the ones that are standard with 18" wheels, only a limited number of these were made - so when he says anni style - he means the exhaust is the style of the one off the anniversay edition mk4 gti.
4motion - 4motion golf - has a different rear valance for standard twin pipes - different to the 1.8T
hope all this info helps and isnt too much to take in...
