Don't ever use DORMAN manifolds on Super Dutys

    Had a big exhaust leak in my truck so I decided to replace them with a DORMAN manifold. Worst mistake ever. 6 Months later, the F**king thing cracked in half by Bank 3 cylinder. Not sure if the Casting is weak or what, but hope none of you have to use this manifold. Going to have to find a oem one soon. At least it'll be easier this time around.

    I replaced mine with gibson stainless headers. didn't want to mess with another set of manifolds only to have the same problem again. got a nice little power boost too.

    Lol yep I put one one once and it was cracked out of the box. They are worse them the junk ford puts on! I just did a 2008 v10. 6 out of the 10 studs had rotted off some pure quality there.
