Some would love an afterburner exhaust! The bad *** biker Leonard Smalls had this feature in the movie Raising Arizona. Now you can really torch tailgaters with a twist of the throttle. Sorry, couldn't resist - just kidding, man.
Obviously you're igniting unburned fuel in the exhaust. A starting point is to read your plugs to see if you're too lean or rich, then troubleshoot the carb from there. Other factors may be exhaust joint air leaks that promote the famous decel pop or ignition timing. Hard to say without more data, but I suspect the carb may be a mismatch.
