Was over at The Other Guys Performance Products and they just completed Header R&D on a box stock '01 Ford F-150 w/5.4L. Awesome! Also saw the before and after dyno results.....18 HP and 20 TQ Wonder what they would do with S/C? Pretty impressive if you ask me. They said they would be available in about a month. Check out their site at www.theotherguysproducts.com I'll definately get the headers for my truck!

 

What did the power 'curve' look like though?? Did it trade tons of torque down low for those numbers?? I'd be interested to see because I would love to get a set of Edelbrock headders but heard too many people say they lost low end torque. Just checking.
