I planned to do nothing to my gti but after listening to the sound of the milltek on another car i just had to have one!
I have heard that a non res is too loud when fitted with the downpipe so i got just the cat back system, it's really starting to sound great now after 5000 miles but soon after getting the zorst i had the uncontrolable urge to get it remapped!
the upgrading bug is well set in now but a lack of funds holds me back from time to time.
saying that, i have just bought a set of eibach's for it which will be fitted once the warmer weather comes as i'm a bit soft for laying under the car in the cold these days!
