Magnaflow catback is hard to beat for the price. The Bassani is a little better quality unit but cost 1-1/2 time as much.
If you want a catted x-pipe go with the VRS, same as the Magnaflow but a little cheaper in price. If you want a off-road unit the Dr. Gas X-pipe is the best hands down.
You have to decide if you want to stay emmisions legal or not. If not go long tubes. I would say use Kooks at this point and time, if staying with shorties for emissions the JBA's post the best numbers. I can't argue that either.
As for DR's they woln't handle well on auto-x or road racing. The side is just to soft and will cause a snap over steer feel to the car. But for straight line traction the DR's can't be beat for a radial. Nothing else will come close.
