Wheezing...not in shed...no URI symptoms?

[CALM Pythons]

My male banana is making a whistling or wheezing sound every so often.. some noises are louder than others and it is not consistent. He is not currently in shed and isn't exhibiting any signs of a URI (very active, eating eagerly and regularly, no mucus or saliva near the nose or mouth, doesn't open his mouth like a "yawn").
His hot side is 89, hot spot is 90, cool side is 78, I use cypress mulch for substrate and it's totally clean (since he poops in his water dish or ON MY BED!)
He is currently cruising around my bed happy as can be and i have checked his mouth and nose several times...I did see a small fiber or hair coming out of his mouth (probably from my clothes, or he likes to rub his face in my actual hair).
Could there be something benign in his nose, should I take him to a vet immediately?
I know this isn't a normal sound beeps make but he seems 100% healthy otherwise..

One of mine has had a Click for 1.5 years. Drove me nuts all last winter and still (Today) i'll say to someone thats with me when I have her out "did you hear that" hahahaha. My wife doesn't even answer me anymore lol. Mine does it when her tongue comes out, its just the way she is.. Since you mention a piece of stuck shed my first guess would be a tiny piece in the nasal cavity or the shape of the cavity itself. Some snakes make noises because of this. Keep a eye on it. If no symptoms I would not be overly concerned.
