Inline 6, stock engine. It has the pulse air system. Rebuilding, swapped engines. Want to clean up engine area. Ran great completely stock but wanting to reduce engine clutter and install new exhaust that is more efficient. Worried about vacuum problems if I let the downstream air injection tube and the upstream air injection tube hang free not connecting the catalytic or exhaust pipe. Thanks for all your help
have the same problem?
