air pump ?
I know this has been asked 1000 times, I probably asked myself, but ehy i'm old so humor me. What size plugs go in the exhaust manifolds when you take the air pump off? I thought it was 1/4 " but I don't remember

You need 1/4" flare plugs (not pipe plugs) to ensure a good fit.
The stock pipes are made like this, so having a flare plug is the best way to seal them off.
