OK ... I just got my MAC FIPK (swept chrome tube - just like AirForce 1). I looked inside the tube and saw that it is raw (no polish or coating). Here's the question (actually a question inside of a question)... should I

(A) consider a way to polish or coat the inside of the tube (make it slick) for better air flow; or ....

(B) let it alone because the raw surface will allow some turbulant flow to help the air mixing in the intake?
