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.

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...
