Hey i was looking at the edelbrock TES shorties... can i just plug the AIR tube and the y will bolt right up to my factory dual cats?? my cats are gone so i was wondering if a flowmaster merge would work well or just weld some pipes up???

 

If you get the Edelbrock headers that are specific to your engine application then they should bolt right up to your stock cats. I am not sure if they have a dual cat option though for L98's. If that is the case I would look at the Hooker 2055's and convert to a single 3" cat. That is unless you need to retain the dual cats for inspecion.
