Passing Inspection? with HJS HD 200cpsi cats
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
