Just the standard GT back end. It’s brought the car alive. Since getting the car I’ve always thought that it lacked sound. Not talking crackle and pops just general sound to accompany the performance, most notably under 4K rpm. As you know to hit that sweet spot to need to be pushing on and that’s not always practical, if you value your license.
What this has done is brought it down by 2k. On a neutral throttle ie steady 70,80,90 there’s no perceivable difference but as soon as you hit the gas it’s very noticeable. Also on start up...... especially when on the train on the way back.
Decent little overnight road trip too. Lunch in Ypres on the way and an overnight in Bruges, where we had the pleasure of paying 28 euro for a bottle of £5.00 wine!
