Default Single out vs Dual out exhaust - which models are single, which are dual?
I see that some 911s have factory dual outlet exhaust and some have single outlet, is there some option package that designates a 911 as having factory single or dual outlet?

Ah, okay. So the pre 964 cars that have dual out did not come from the factory that way.

Thanks!
