    Default 6.0L long tube headers

    Well I've decided I want a set of long tube headers but I can't find a decently priced set that fits my 6.0L! On it says the pacesetters fit but when I searched that part number on jegs and summit it said that header is for the 5.3 and 4.8?? Has anyone had success using these pacesetters on a 6.0?!

    Well I couldn't wait any longer and pulled the trigger on them! I got them from jegs because since they ship out of dayton ohio they always come to me really fast so I'll let you all know how it goes!

    I think they'll fit Nathan cuz when I look at some of the other manufacturers sets they say they fit up through 6.5L, same exhaust port spacing

    They will fit and work. The 4.8,5.3 and 6.0 share the same exhaust maniflods so the headers will fit.

    Before you start to install them check if they include O2 sensor wire extensions. Most likely you will need rear O2 extensions.

    Thanks for the confirmation guys!

    As far as the O2 sensors I already have a custom exhaust and those O2 sensors are welded in the pipe two places after the headers so if I continue to run that piping will I be ok?

    They give you extra wire and connections to extend them, but on my truck i didn't even need to extend. It was long enough to move to the new location.
