STL/MO how to pass emissions/inspection with mods?
How do people in STL/MO deal with the emissions testing if you have deleted cats or supercharged? I've never really had a clear answer other than to convert back to stock for the test. A little rough to do with a SC...
MO stopped testing cars as old as my RX-7 was so I put it out of my mind.
