So last night I started installing a Flowmaster American Thunder exhaust onto my F150 Screw 4x4 short bed. I've been taking pictures and video to show how I've done it and the issues encountered! Everything should be up tonight when I finish or tomorrow afternoon when I can organize it all! I got the stock muffler off last night with a sawzall and an impact wrench and then drove it around the neighborhood a little. SO LOUD! But it's garaged now and waiting to sound even better!

 

Okay so here's the link to my photo album showing all of the steps to installing the Flowmaster exhaust!

This follows the paper instructions which can be found here:

And here's a video of the sound differences between stock, no mufflers, and the Flowmaster!

 

And here's one of me messing around with the truck the day after I put on the exhaust:
