March 11, 2010I have an 06 SuperCrew xlt with the 5.4. I plan on putting an exhaust on it soon. I would like a nice low rumble at highway speeds but a good growl when I hit the gas. Let me have some ideas, either SI/SO, SI/DO or DI/DO. I am open to ideas, but I would like to keep it between $300/400.
