05-06 5.4L 3 Valve Headers on Sale
 

Doug Thorley Has a bit too many of these headers on the shelf. I screwed up and doubled the work order on accident, so I need to clear them out. While supplies last, these are new in the box with hardware and are not blems or returns. Retail is $844 and the forum special is $499.00 plus tax and shipping. This price is for a set of chrome plated headers.

now are theis for the f150 5.4 and will they bolt up to stock y pipe ?

The title says "5.4". :) Shorties are, by default, designed to fit to existing exhaust systems so I think that shouldn't be a problem. Later....

These headers fit the F150 only. They will not bolt to the factory exhaust in the F250 or F350 with the 5.4L engine.

My question would be does the F150 have 2" or 2.5" collectors from the factory? The reason that I ask is because another manufacturer states that their will bolt directly to the OEM exhaust with a 2" collector...

The user asking had "F150" in his signature and that's what I was addressing. I never said it would fit an F250/F350.

Understood... my bad.
