I've narrowed my search for some headers down to two, LT ones are pacesteer but one LT and one shorty (JBA) headers, obviously I want the LT for my 4.6 for all the low end power and performance but it is 2wd and the LT are only for my 4.6 if it is 4wd, my question is does anybdy have any knowledge that the 4wd can be put on a 2wd? and if so or if not please share if theres modifications that have to be made or if it is just a dumb idea and just get it over with a buy the shrotys,

shorts part # JBA1687S
LT part #PAC72C2328
