Mostly, the 993 passengers side side flanges are rotated 90° from all earlier version. If you use oem 993 headers on your engine it's easy enough to do.

Yes, they do. For a 3.6 or 3.7 street motor you will want ~1 3/4" primary tubes.
Your cheapest option is oem 993, if you want to spend more B&B headers but not B&B mufflers
