I just got an 08 f150 5.4l xlt screw, with 6.5 foot bed. Checked with many different places and everyone in telling me they dont make a system for this truck, i find that hard to believe. any suggestions the louder the better.

 

Buy a muffler and tips and take them to the exhaust shop and have them install it. This way you get the muffler you want, and tips.

 

A good Muffler shop should be able to fab something for you. I've never bought an off the shelf exhaust for anything. You want loud get the MagnaFlow MagnaPacks....had them on my stang...talk about wake the dead and scare little children and old folks!!!! Also I would do a true dual with an X pipe...I'm sure this will spawn a whole diffrent conversation.

 

Just don't go to Midas. They don't have any mandrel bent pipes, just crush bent.

 

go true duals with no mufflers, the loudest setup you can do without messing with the cats
