depends on the muffler you're using. if you're goin with the flowmaster camaro muffler like a lot of people have then it would look pretty sweet with dual tips. but if you're using a straight thorugh muffler i'd personally go with a single and put in a resonator up stream to tone it down a little. also depends if you've made up your mind about the turbo or not. if you go with the turbo you'll definately want the straight through muffler.
