I'm not sure what it is about the internet where people who don't get the answer they want to hear just keep asking differently, hoping they'll find someone who gives them something they want to hear.

I took this screenshot because Tapatalk wouldn't let me load the video I originally took. Anyways my exhaust system (UEL catless headers, high flow fp & custom catback) is being vacuumed into the car via this bar (right behind the rear bumper) and in turn coming into the cabin while driving with windows down. Anyone know what I should do? Cars naturally have holes to release air but this is not safe to drive in. I blasted the AC, closed all windows and closed my garage door with car off, hovered a cigarette around the bottom of car to see what made smoke move this most, and by far this bar had the most movement. I also put a little trees car fresher in my spare tire well and my whole car smelt like the "Black Ice" scent when I rolled the windows down. Any help is much appreciated. My chest gets tight when driving. This doesnt happen with a stock fp only high flow fp. Thank you!!

Something does not make sense as newer cars are designed to have positive pressure inside the cabin. Opening the windows will change things as there can be outside air moving around the car depending on speed. But still air should not be coming in through the one way flaps in the back.
