2wd and 4wd headers? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

what would be the difference between 2 wheel drive and 4wd headers? I noticed flowtech has a part number for 2wd afterburner headers and a different part number for 4wd afterburner headers.

Crossmember/ control arm clearance from what I remember.

well I got a pair of doug thorley's for a 2WD and tried to put em on my 4x4.. the collector would hit the rear shackles.. So I took a torch and heated em up and bent em to clear the shackles.. Thats what I run on my truck now. BTW they were used, I didnt modify new thorleys

hope that helps.. they ARE different

Yeah they dont quite fit, the usually bump into shackles like Capt said, or onto something else thats tottally inconvienient...
