Mushroom elbow.

Just checked with my NAPA guys. 41378 is the right number. $28.49 for me. I like it. Gonna have to put a couple on.

NAPA here won't order it, referred me to a local exhaust company. I just ordered it on the link in this post.

very cool. glad I could help out. I reused the clamp clamp on the elbow in the eng compartment and just put the mushroom on the elbow without a clamp so if I need to extend it or get to it to block the motor on a runaway situation it comes off easily. and we all know these trucks ownt go fast enough to blow it off bc it does have just a bit of tightness.

Added the Napa 4" elbow to the intake this fall. Thought I'd post some pics.

looks good. I slid mine in about 1/2" more to hide the swell in the pipe on the air cleaner housing. I like it though.
