Exhaust pop... Help

I think it's normal. Mine will pop when I for now reason just rev it. My V8 Ford also did it.

It has to do with a lean condition for that instant while the fuel is shut off (throttle position says to) and the rush of air is still occupying the exhaust (therefore all air/minimal fuel). There is more science involved than that, but you may get the idea.

Also, check for any areas of possible exhaust leaks...doesn't take much to cause pops. Assess your manifold and all the joints/clamps and look for cracks/soot. Otherwise, like 08Canyon indicates, it's normal for lean condition.

Ok, thanks for the advise guys
