Jerry, That is not what I understood, but I'll take your word for it. I also would mention that I Muffed the name, I intended to reply to Rusty ,(since you, Jerry are well aware of the going's on with the VAM.) If Ed DIDN'T put the center tube thru to the tail pipe the VAM simply WOULDN'T WORK!  The center tube must be placed in the center, (in fact partially inside) of the tail pipe. Did you get the jpeg?
