Exhaust little pops when decelerating
Hello, I recently replaced MANN air filters with some aftermarket ones and started hearing little exhaust pops when I let off the pedals after accelerating hard. I have replaced secondary resonators with straight pipes and main resonator was replaced with X-pipe. I checked air filters and engine and everything looks okay and back in place. CLS550 2014 4.7 M278 engine.
Is the new air filter letting too much air in or are these little pops in Sport mode ok? anyone else had similar experience?
