I'm getting one of these on mine in the summer when I've recovered from the recent bill on the Mk2.
However, I can't decide whether to go for res or non res. I don't want it to be quieter than the OEM one but then again I don't want it to sound like the lad next door's 1.0 Corsa with a drainpipe on the back i.e. ultra loud and stupid. A bit more grunt than standard is fine.
From odds and sods I've read on here before I'm erring towards a non res but what do you all reckon you lot who have one?
