skunk 2s aren't bad but its all mostly preference, I drive a stock EX but also have a integra LS with a tanabe concept G exhaust and I love it. Tanabe is good for low sound emission so if you run into anal cops they have a smaller chance of pulling you over for it. I personally am a big fan of Tanabe and Apexi really, but it depends on what kind of sound you want coming out of your car.
