Not suitable for exhaust and emissions

Poor casting and/or machining. The casting hits the block before the ports can dock. I tried 3 of them, none worked, even with a thicker pad. The collector is sold under different names, but they all come from the same Chinese assembly line.

Pros

Excellent overall performance

Cons

Minor problems
