I ordered the SD headers, is there anything else I should need like a better downpipe from ZZP or a ported rear manifold?

Headers come with everything...why would you need a downpipe or a PEM?

I didn't see a downpipe maybe it looks different than what ZZP offers or I am just stupid.Stainless SS Racing Manifold Header Exhaust Grand Prix GTP Regal Impala 3 8L V6 | eBay

I see now "Headers – Installing headers means you don’t have to worry about the Powerlog, U-Bend, or Downpipe. Flow is unmatched by any other exhaust setup and there are many brands out there to choose from. I have Pacesetter’s and love them for the price. Recently SS Autochrome or even EBay companies just as DNA or Speed Daddy have came out with SLP knock off headers (They work great for the money)...choice is up to you but if you'd like to know more...follow the header thread linked below. Cost: $195+
