For the Price I'ts Perfectly Fine.

ATP® 101121 - Cast Iron Natural Exhaust Manifold

Expect to do more work before mounting it up. I had to grind the ports out quite a bit since there was so much extra material in the port openings. I used a Dremel and some grinding attachments. I haven't had any issues since the install.
