i got a 460 with duals right now. I was wondering if i used my stock y pipe at the front ran it down one pipe then into say a flowmaster 40's or something then 2 pipes out the back. Would that work and would there be any complications or how could i do it?

 

Interested in this reply as well, I want to use the factory y pipe to dual it out the back sides of the cab. just curious how to go about it with the gas tank in the area....
