Re the warranty, I was told that the factory take the view that anything other than factory Stage 1 exhausts will invalidate the warranty. I would have gone for G56 exhausts otherwise myself. The G56 ones are definitely less noisy than the AR Motorsport ones (which took some getting used to but which I do like).Whichever ones you go for, you won’t regret the better performance they bring.
Shaun, this is with the AR Stage 1 exhaust. I was testing the new tyres and the rattle that persists and gets a bit worse.
