I'm looking for an exhaust that will make my 2011 5.0l a little louder now ive heard suggestions like flowmaster or magnaflow. now ive also heard u may have to change the way the fuel is regulated if u add a bigger exhaust. though ive heard the opposite 2. so does anyone have any good suggestions on the right exhaust and if changes the fuel regulation? because i plan to do this in the near future.

 

Pretty much an aftermarket exhaust will make it louder. Just buy an axle-back kit. Changing mufflers doesn't require any modifications to the fuel system.
