[QUOTE="Alex_225, post: 31088, member: 79"] Sorry for the late reply, forgot about this post. I've not noticed it happen since, although the one down change I did notice this noise on was matching the revs at about 4k which is higher than your average down change. It's certainly not a mechanical knock such as engine mounts but does sound far more like an induction/exhaust type pop. Hence thinking it could be the induction kit!? My Lupo used to do the exact same type of thing on a blipped down change but that was with a new manifold, induction kit and full exhaust system. I wouldn't expect the Twingo to pop on a down change through the stock exhaust. [/QUOTE]
