66 Dart, Sanderson Headers...what exhaust

Hi All

I've just purchased some Sanderson Headers. I want to know what you guys think I should do exhaust wise? I'm based in the UK, and have seen some of the twin pipe systems but can only find them for 67+. Does anyone know if I can use a 67 on a 66?
It would be great if I can get the full complete set for shipping ease etc.

Thanks
Steve
Because 66 and older cars didn't ever have duals, the transmission crossmember is notched on the drivers side only. You can either modify the crossmember or have pipes bent to hang below the crossmember. There are threads here about all of that.
