Thanks for the replies everyone.
Yes my gti is manual, and I've read all the stuff about the clutches not handling the higher torque maps.
This is drawing me towards the offer awesome have for an APR stage one map and updated clutch install for £1.5k, only thing is it would mean driving a few hundred miles up to Manc, I'm near Southampton.
Has anyone done that deal, is it reasonable?
I've watched loads of videos on the exhausts and to be honest they all look and sound great. I personally prefer a raspier sound rather than a deep tone if anyone can point me in the direction of that type sounding system. I'm only looking at going stage 1 with a cat back....
Thanks again
