    Icon13 Another Cracked Exhaust manifold

    I purchased a Dorman exhaust manifold from Amazon back in Feb of 2017.

    I have not inspected it, but I hear the sounds of a cracked header, again.

    I have the Brown Dog motor mounts.

    I've read that ALL exhaust manifolds crack, even the 400 ones. I'd rather crack a 100 personally.

    If engine movement is cracking the manifold (all of mine have been cracked at or near the collector) I was thinking about doing this.

    Has anyone had luck with an exhaust manifold NOT cracking for a few years at a time?

    My XJ still has the original exhaust manifold and no signs of cracking whatsoever.
