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?
