Not meaning to offend, but it would seem you need to more carefully research and read.

First of all, it's VERY difficult (I won't say impossible, because sure as heck SOMEBODY'S probably done it) to get smoke out of a smaller sized glow motor, such as the LA 46 you mention. First of all, they tend to run at high RPM, blowing the oil out of the muffler before it's had time to get hot enough, and second of all, a plane powered by a .40-sized motor isn't likely to accept the extra weight of a smoke system, both points made early in that article I linked for you.

Second of all, the muffler you've referenced is for a COMPLETELY different (Gas, not glow, and MUCH larger) motor, as it clearly states in the product description.

So...as I say...I certainly don't wish to be rude, but do please take a bit of care to read and research thoroughly.
