Block the AIR tubes?
Will blocking my AIR tube at the cat end cause any problems with exhaust flow at the manifolds or with the AIR pump??? I'm running without a cat and want to keep the tube for my next etest in place but dont like the leaky exhaust sound it gives off sometimes.

You can block it off. It's not going to hurt anything. Is your emission test just a visual test? If it's just visual, you can block up the inside of the tube then hook it back up. That's what I did to mine, but Virginia only has a visual inspection.
I dont have to etest again till next year tho.
