   i would say 2"
   
   i make this judgement because that is the bore they use on the Super 1600
   cars, a lot of investment goes into their performance.

   Definately 2inch.
   
   Even Peugeot only stepped up to 2.25inch when they built the Maxi spec cars.
   
   All the group N systems are 50mm (2 inch)

   I would say 55mm external diameter so the internal will be about 52-53mm depends on wall of the pipe. 60mm is too large for 1600 engine. Will be ok if you are using nitrous or highly modified engine.

    2" for near standard n/a imo
    
    any smaller and it will restrict the exhaust gases, too large and it buggers up the 'pulsing'... ie, you lose power
