You can either get a catback system or you can just go the cheaper rout and buy a universal muffler(which means it will fit a wide variety of cars).I have a muffer made by magnaflow on my 93 civic hatch and its a universal muffler.It sounds awsome.And also you could put a cold air intake on your car which will give a little more sound and more performance.Also help with gas mileage.haha.
