They come with all the gaskets and bolts for installation. They are from Ebay, but the quality is pretty good. The welds are decent, the bends are good, and the metal is in great shape.
I'm only selling because I doubt I'll ever have time to do this, it
seems my time has been consumed with replacing some ailing parts, so I'd rather see someone use this rather it just collect dust.
$100 + shipping OBO.
