If you check out the classifieds on this site, you'll see Chazz has an exhaust system for sale. All 3 you listed are good, but Borla has the most pieces, and I think it's also the heaviest (not sure though).
I would also check out the modifications sections and see all the threads about exhaust. Track just got a Greddy, and I've personally seen and heard the Injen SES (which is nice).
