I picked up a similar one thats made by Dorman. I got tired of dropping money on headers that would eventually crack anyways. The last set I went through were Rugged Ridge. They made it about 3 years before cracking worse then i've ever seen.
Im happy with the Dorman right now. They appear to be well made, and come with a flange gasket and manifold gasket. I suggest upgrading to better gaskets though.
