not true, south eastern towns in WI have to go through a emission, just a smog one, there is no visual nor anything is asked about whats under the hood, they don't even look to see if u have a cat, or o2 sensors, they just put it on there lil tester deal and rev the car up for like 3 mins and thats it. "well for 1996+ years," thats how it works in kenosha, other than that i dunno if it will pass, just clearifiying that WI dose have emission testing

. we all aren't hill billys as they are up north.
