I own a 2016 Infiniti Q50 and I’m interested in buying parts that would allow me to backfire/get that popping noise. I am not a car guy at all so I have no idea what I’m talking about. I know that there are only a few discussions on here about backfire, but I didn’t get all the information I need. So far after some research I’ve found that I need downpipes, a racechip tune, and a heat exchanger (I live in Florida and my cars blacked out). I was wondering if anyone can help me figure out everything I need before I go spend a bunch of money. Thank you in advance.
