I have a 97 WS6 and I just bought a 94-95 style Borla cat-back. Now I don't plan on running cats and have an offer on the table to purchase SLP shorty headers and y-pipe Part#30017c that came off a dual cat 95. My question is, how do I get this system to work? What will I need? I think I need an off-road pipe, the SLP install kit, and o2sims, correct? What else do I need and how does the y pipe differ from single cat applications? Thanks!
