From those choices I'd say it depends on how loud you want it and the look you want. The Skunk2 is the loudest of the 4 and has a canister muffler. The other 3 will definetely be quieter and I believe they are all oval mufflers.

I have the Skunk2 on my EG hatch and it's a great exhaust, but with a header and test pipe it's pretty loud.
