Emissions in MN

R Dogg 56 · July 21, 2003

What do we need on our exhaust systems here? If memory serves, didn't Uncle Jesse do away with all testing for vehicles? Do we still need cats and if so, how can we "get away" without them?

Just wondering.

Minnesota had testing but not anymore. So you can do anything with your exhaust systems here and never get in touble, as long they dont start testing again.

Can the cops still get you for not having cats and/or mufflers?

Obviously the police can pull you over for no mufflers if it's breaking the noise ordinance. Cats won't make a difference and they wouldn't know unless they were specifically doing an emissions check....which they can't do now anyway.

First off, any emissions equipment on your vehicle is a FEDERALLY mandated piece, not a STATE mandated. A catalytic converter is a emissions control device and is mandated by the FEDERAL government to be on ALL vehicles. Now I understand what you're gonna say, but we don't have testing in MN. Right, your state government doesn't test the "effectiveness" of the emissions equipment on your vehicle. That doesn't mean it gives you free reign to remove everything. If for some bizarre reason any member of the law enforcement community or a Federal authority should pull you over, find you have removed your cats, then you will be subject to the fines as prescribed by the Federal government.

Secondly, removing cats may net you a few ponies, net you a MPG or two, but you lose a lb-ft or two of torque and you generally will have a "raspy" sound to your exhaust note. To me it's a 6 of one, half dozen of another scenario.

And trust me, I'm not preaching at you to keep them on, just explaining. If we didn't have emissions testing here, mine would've been long gone.
