I see that a bunch of you guys have O/R exhaust on older 5.0s...how do you get them to pass IL emissions? Id love to go catless, but I dont wanna put all that sh*t back on when its time for a emissions test..help

 

There are no emissions here. I'm in southern Illinois (carbondale)

 

U just have to switch in between the cats and the h -pipe ,or u could just get hi- flow cats
