Did they do the stage one flash ? Check the flange nuts at the exhaust where the pipes attach to the head , should be 12ft lbs , a leaking gasket will cause popping . Try disconnecting your 02 sensors and see if that makes a difference , if not reconnect them , if its better , leave them unplugged .

Keep in mind when changing out the stock exhaust , some popping will be present , there is no avoiding it .

Mags is correct...you can't really avoid it. There are some things you can do (idle air valve, PCV, tuning, timing wheel, etc...) to decrease it but inevitably it will pop some. Try not to ride it like a sport bike and you will see less popping

what Mags said but it might take 3 or 4 times to get them tight. Check after each ride

Minimum right wrist movement between shifts equals minimum popping.

Better you should ask, Is it Snapping, Crackling or Popping?
