The overrun on the exhaust is louder - yes. The brakes are a massive step up from the regular ones on the S - yes. Seats are fantastic - have been looking forward to the thigh support for ages. The GP also teases in the way the whine really starts to kick in at 4,500 rpm, just as you are obliged to change up. Did a couple of hours on the motorway today and mileage is I guess 170, with an indicated range of another 170 to go. The stereo isn't totally useless either.
Lots of head-turning happening too, either from the pure looks, or the exhaust note/pops afterwards. Only downside is that it's going to take me ages to run the thing in as it will be in airport car parks for two weeks out of four over the next couple of months
