Yeah I agree with ^ muffler won't add to your performance. Basically just a noise thing. If you add an exhaust you should probably add a cai or a higher flowing intake. The factory exhaust is made for the factory intake so if you don't have more comin in then a bigger exhaust won't really so much. Especially with the restrictive exhaust header.
