When idling there’s audible burbling / popping from the exhaust and they can be felt when sitting in the car, especially when I’m focused on the sound. Don’t know if it’s normal, car is at 180,000km bone stock except a street legal cat back, basically original system just bigger pipes since the original system was ruined. Anyways, I’ll put a video in the post so yall can hear it. Thanks in advance!
