Since its a 1J then the single is prob going to sound better, and less weight. You can always do dual its your preference.

The single exhaust would weigh less. Duals look better though.

If you go with the single, fill in the other hole on the bumper.

Single ruins the SC making it look like just another regular car on the road. I have the stock dual exhaust it looks more sporty & sexy

remember you want a straight exhaust (less bends and restrictions for the gases to travel through) so since your car has a 1j swap, all the exhaust comes out from only one bank of the engine... why mess with something straight and add an unnecessary bend to make it dual?
