This system is made in Australia to suit the Megane 4 280 300 RS non GPF
it is a 3" inch high flow cat back exhaust system, designed to work with or without a high flow cat to get the best flow, and sound, while still being non booming in the cabin. check out the video to hear how it sounds.
see the dyno sheet for this car with this exhaust, green cotton panel filter and tune here.
