Exhaust gas velocity is only important in the exhaust manifold prior to the collector. Anything after that has no effect on exhaust gas scavenging, so you can make it as big as you like. The law of diminishing returns applies here though; there comes a point where making the pipe bigger does nothing except make the car louder. 2" is probably plenty for an atmo 1.6 litre engine.
