For my TT46, and ST45, I use a can that 6.5" in length by 1.75" in diameter.

for my 40fp, I am using a can that 6" lenght by 1.5" in diameter

all stingers are 1/4 O.D. (outisde diamter) and my inlet pipe are 3/4" O.D."

As for stinger tubing, I use 1/4" copper refrigator tubing I found at Lowes in the plumbing department, at Lowes, they sell it by the roll around 40ft, which is way to much, are you can buy it packaged up in 12" sections.

I am running moosecan on every 2 stroke I own.
