I suspect you have an exhaust leak.
Basically this popping is caused by fuel igniting in the exhaust. The added air will cause it to ignite rather than the hydrocarbons reacting with the converter.
The other possible cause is the vehicle is running rich. You can inspect the o2 sensor data with a scan tool to see if it is negative. If the fuel trims are negative that means there is less oxygen in the exhaust due to the higher fuel content.
However, I would start with looking for exhaust leaks.
