1. Looking like crap, though, would not be the case for non-SVT rear bumpers.

2. The rear Y is just another source of turbulence, but if done well, not much of one.

3. If I (in my limited knowledge) were designing a system for best performance, looks be damned, (or for a non-SVT body), I would go with a single pipe with outlet on the right, or a true dual.

1. He has an SVT.

2. Right. If well done, not enough to notice any performance difference.

3. Right. True duals are your best option. "Technically" single exhaust would be a little more efficient than quasi dual since it does not have the Y split. However any performance difference would be very hard to measure.
