Yeah, since the 05 came out people are getting a premium for take-offs. As for the "performance" stock mufflers, they are better than the one on the stock V6 exhaust, even one of them as far as I know. Since I broke down and am renting a garage at my apartments now, I can say they sound pretty nice, though subdued. If you can find a good deal on the takeoffs, it's still cheaper than buying something else in stainless.
Lowflyn, you got one hell of a deal on yours. The mach tips look so sweet!
