I need to know if I get a stock tuned port dual cat set up, what modifications(if any) will I have to make to get my stock RS air tube from the smog pump to connect to the one on the dual cat set up. Do I also need to get that tube from a dual cat car, or are they the same from the smog? Thanks guys

 

I could be wrong but something is telling me they are almost the same. The only difference that I have seen is that the single cat has the pipe connecting directly to it. On the Dual's, the pipes come out of the cats and plug into a block that sits on the exhast pipes(stock), this block then coverts into 1 pipe. Actually now that I'm thinking about it, the stock dual setup will come with the AIR tub already on it. The tube will come appart on the back side of the motor(against the firewall), you shold be able to connect them at this point.

Hope that helps!

 

Thanks, I'll check it out when I get to the salvage yard
