LS1 headers Diameter?

Ok, Im making my own cutoms headers and Single exhaust piping... so cause the engine is on a 240sx I want to keep the Single Angled Exhaust...

In mm, or Inches, what should the headers be in Diameter? and what should the remaining Single Pipe be to the back of the car?

My car is Completely stock, and will get some good HeadWork...

Thanks

I made my own and used 1 3/4" for the primaries. Out is your choice, 2 1/2 for something stock in a dual, I would do 3" if you are running single back.
