I like the R32 front end, I'm a massive fan of the chrome though, by the time mine is finished it'll have a fair few chrome touches across the car. However if you really want to get a GTI front you might be lucky enough to pick up an OEM one in the right colour to keep the cost down.
That was a good stroke of luck when it comes to the Miltek exhaust, looks to me like all the mods that were done before you bought it had no expense spared which is usually a pretty good sign that the car has been well cared for.
