wat size exhaust am i best to get to get best performance out of a 1.2 nova with 1.4 head and cam with a 1.3 inlet and carb?
the same diameter exhaust is used on all factory petrol novas....
what manifold are you using??? the 1.3 4-2-1 works pretty well, especially if you make sure that the 2-1 bit is cleaned up for decent flow

take the head off and put the 1200 one back on there if your after performance.
