Magnaflow's straight through mufflers are the best, IMO, provided you keep the pipe to 2 or 2 1/4. It's a bit louder, but still very quiet. A proper muffler should work like a firearm silencer/use baffles and dispersion and not make the exhaust run through a maze of chambers.

http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=7547I have this on my 4Runner. Very nice. This is more money but appears to be the best overall design. Yeah, it's chrome. The shop had this for $20 more and said it would sound better. The chrome will rust soon enough.
http://www.magnaflow.com/02product/shopexd.asp?zone=main&id=7631This would also work fine I bet for a LOT less money. I honestly doubt if a 22R or 22RE has enough power to even need 2.25 inch(2 inch would likely work just as well for a DD), though I do like the sound of straight through - like exactly half of a V8.
Their cats also are very nice. Both makes for a very nice non-tinny sound. Though, yeah - it's obviously a small 4 and not a V8. It's NOT going to ever sound like a Chevy 350.
http://www.car-sound.com/02product/shopdisplayproducts.asp?pulldown=csHave to weld a bit but this is about 2/3 the cost of a direct fit one. $160 vs $260. That's about half what the OEM cat costs.
The two together are about $250 if you shop around. Add some pipe and
and enjoy.
