I noticed today that my exhaust is making a fairly soft, quiet "pop" every 10 seconds or so when at idle or very low RPM. Car otherwise appears to be running fine. Anyone have any insight into what this might be?
Exhaust popping noise?

muffler bearings are shot

might have a little bit of unburnt fuel in the exhaust, then all it takes is a real small exhaust leak to let in a little oxygen....... pop

No wonder Canada has such high tax rates...
Figures. Canadians need to stick together.
However, I have it from an excellent source that the Viper muffler bearings are of lifetime qualty and unlikely to cause this popping. More likely the warp drive disengaging during decel manuevers.

Check the spark plugs.

Possible rich condition, also check to see if the o2 sensors are working properly.

letting off the gas is normal to hear a little pop, just idling, shouldn't hear a pop.

It has always popped when decelerating in gear at around 2000 rpm or so, but I noticed this idle popping yesterday for the first time. The weirdest thing is, it didn't do it this morning.
Could it be a fuel quality issue? I filled it up with gas at a station up in the North Georgia mountains a couple of days ago.

Could be. Moisture in the gas will cause the popping sound at idle.

I just pulled in and my 2000 GTS, for the first time, is popping out of the driver side exhaust 10-20 seconds apart. Drove it all day and it didn't do it. Plugs have a few thousand miles on them, the entire exhaust was just re-done. Odd, I'll have to see if it does it tomorrow.
Popping is from unburnt fuel in the exhaust. The most common cause would be plugs or plug wires. For an NA car that be where you search, if nitrous or sc, it gets more complicated. Pull all the plugs to assess the problem.
