In order to help retain low RPM torque, you want to avoid full dual exhaust systems as the decrease in back pressure tends to cause a loss in low to mid RPM torque. A good cat back, Single In/Single Out or Single In/Dual Out setup is a good way to help pick up a little power on the top without killing the lower RPM. Magnaflow is a good combination of price and quality, and is probably the most popular brand with the F-150 crowd.

Bring back  Windows™ XP and 7. 
Windows™ Vista and Windows™ 8 is a pain in my a$$! 
Windows™ 10 is only slightly less annoying! 
Windows™ 11 is garbage! 
Much to my surprise, I'm actually quite enjoying Linux!
