Is this the cylinders misfiring while downshifting? How do I fix running rich. I have reset ecu 2 times.

Have you checked your mid-pipe for exhaust leaks, especially under the heat shield? When it happened to mine, one of the symptoms, besides sporadic P0420 DTCs, was occasional backfires during deceleration.

Same! I love it lol If I gas it and let off, the exhaust will gurgle and back fire as the car downshifts. It also does is when I'm slowing down after driving hard. I don't have the F-Sport exhaust though. I got the resonator and mufflers removed.

Nope, haven't check I have no CEL and no VSC lights. I only notice it when its a pretty hard brake. If its slowly decelerate it doesn't backfire but I'm worried running rich might cause some problems.

I always backfired with my f-sport. Like you described and especially right before coming to a stop. I put over 45000kms on it with no issues. Vancouver driven also if it makes you feel better .
