Vacuum Line Routing
Hope everyone is doing well. So, I have a vacuum diagram for my 84 MC. I'm trying to confirm the routing. Per the picture, is the top port of the EFE/TVS valve/sensor mating via a t-connector to the "L" hose from the carb before they connect through the merged single line to the AIR management...- G_RIDE_81

Cats or no cats?

New dual exhaust/emissions questions
Hey everyone, got a 79 Monte, I'm thinking of ordering a new duel exhaust and headers kit from jegs. It's a bolt on deal set up. My only issue is I live in an emissions city and my car has a cat on it. The kit has no cats and not finding one that comes with them. I don't really want them anyway...
