How high are the RPM's ? You might be bouncing off the rev limiter which takes fuel away.

off road mid pipe = pops/crackles its normal if you have no cats

Mine does it too. In fact in shoots fire sometimes. I've had it on the dyno and they said the a/f ratio is fine. So I don't know why it does it.

Shifting faster, makes less popping noises!

Check for exhaust leaks.

I was literally about to make this same thread!lol. So it's not something to be overly concerned about? I have an o/r x pipe with no cats.

EDIT: I also just remembered I took out the ram air set up and that may have had something to do with it also. The air hitting the maf may have caused a mismatch. Just a couple of maybe ideas. My back fire is gone and it all started when I dumped the exhaust. Prolly exhaust leak.
