No drone at all but it doesn't sound as good IMO.

Yeah I heard a Corsa and it sounded pretty good, I seen them put it on a 4.6 and dyno it and it put down a gain of 8hp and I think 12ft/lbs.

And as for going staight over to true duals depending on your setup and needs it might have a negative effect on your low end perf.

If I was to do true duals, I'd go with a magnaflow X-pipe and probably two chambered mufflers, running 2.5in pipe the whole way.
