I have just had the MMC (AR Motorsport) Stage 1 kit fitted and it has made the engine a lot more tractable and is definitely much nicer to drive. That’s the good news. The cloud in the silver lining (although some may see it the other way around!) is that it really is very loud. At steady revs (when not accelerating or decelerating) I think it is actually quieter than before but when you come off the gas or go on it, it makes a huge amount of noise. Coming off, there’s lots of snap, crackle and pop (generally good), going on it’s ear splitting (not so good). On the drive back from the dealer, I set off the alarm of a car parked on the side of the road at one point! It is quite fun, driving through Oxford, to slip the car into neutral and blip the throttle and see people jump on the pavement. If you’re of the hooligan tendency, you’d love it, I think. I suspect I will get used to it (and I do really like how much easier it is driving around at slower speeds, in particular) but have told my dealer to hang on to my old pipes just in case I decide at some point that I want to reverse it to what it was. The upcoming Grindelwald trip will be a long test run of the kit. The G56 pipes are a bit (a lot?) quieter, I believe, and I would have gone with those if MMC had not said that any Stage 1 kit rather than their own would invalidate the engine warranty.
