A friend made what looks like a great mod: The "Y" + hoses mounted to the engine with custom fittings and a rubber gasket to seat properly against the lower cowling. It seems to work great and I actually think it would be a safety enhancing feature- without having to undo those pesky little hose clamps everytime you might be more prone to remove the lower cowling and thus check the lower part of the engine more often.

Just (L-)4 fun/ Jörgen

After a while, I just took the scat tubes off. My friend's Cub has the Y-induction inlet screwed on from the front of the cowling, so that it separates from the cowling instead of permanently riveted. When removing the lower cowling, remove the screws from the front, that separates the Y-induction fitting from the cowling. It just hangs there on the tubes. Not original, but makes it easier.

Me too. I thought most Cubs were set up that way now. I just switched to 2" flexible Aluminum ducting like the originals...What a pleasure ! compared to fighting the SCATT spiral wire !

I keep my tubes permanently clamped up front at the induction Y. When installing lower cowl, it takes a little jiggle to get the airbox through cowl opening, then just slip SCAT tubes into muffler housing. Works for me.
