Has anyone put High Flow HJS HD 200cpsi on downpipes and PASSED inspection in USA..
I'm reading the spec sheet on these and they seem to have the same conversion/cleaning rate as regular 400 cell ones but I'd like to get some evidence ..

No cell, pass inspections.. That's all that matters. You are allowed 1 not ready to pass(atleast in Illinois)
Unless this is a visual check you are talking about. If they are going to give you a code, then mind as well go catless if looking for performance gain

USA states are very different. FL to CA is a world apart. Which state?
