That is classic exhaust leak. I would loosen everything up a bit, hold the header on square on the gasket, tighten up the header nut and bolt EVENLY, a little turn each till it is tight.
I just bought the Jardine full race exhaust system and I am also getting the horrendous backfire. I can completely close my fuel screw and the bike still runs. Currently, the fuel does not do much. I am also running with a 48 pilot and a l68 main. What year WR do you have? Isn't the AIS kit on 2004 WR's and later?
Tighten up the rest of the exhaust system and make sure the header outlet is square to the midpipe inlet.
You will be amazed of what the tiniest leak will do, to your jetting and not to mention the flames it would spit!
