Long Tubes passing Emissions

To all the people saying you can't:

Is this strictly because you have to pass a visual inspection as well?

I dont have to, just the sniffer in the tail pipe.

I want to run lt's with the AIR attatchments and O2 extensions. Also through a cat or 2 if I make it true duals.

It is a violation of federal law to relocate the position of the catalytic converters.

If it's just a sniffer test, you'll pass if you get emmissions provisioned LTs.

Re: Long Tubes passing Emissions

long tubes and midlengths will pass emmissions. It's just againts the law to move your cats. In other words, all long tube headers move the cats so you know the answer. Even if you have two cats with long tubes, you still fail. That is unless you know someone or someone is cool with you and just smogs it.
