Header glow is normal.
back fire is different.
I'll let the more experienced guys answer but my guess is they might say check the header gasket..

The glowing header is the "please ride me" indicator light (normal, but can increase when lean). The backfiring could be caused by the header or midpipe leaking, or it may just be a lean mixture. Make sure you have a good seal at those locations. It could be leaner because of cold weather and you can open your fuel screw about a half turn to see if it improves.
