meagan header fits with stock y-pipe right? also if i keep the stock y-pipe it wont get rid of my cat converter so i dont need o2 sim? chicago is extremely gay and actually measures the amount of smog comin out of exhaust so o2 sim doesnt help? tell me if im wrong cuz i r teh noobie.

you have two cats on the stock header that your getting rid of so you will need a o2sim if you wanna get rid of the CEL, and also the o2sim wont help with the smog

I have heard a number of times that even with the two cats on the headers gone you can still pass an emissions test... If its like it is here (California) you would fail the visual test though.

damn... well i guess i better give chicago smog tests a call... cuz i know for a fact they check the actual smog coming out of the exhaust unlike certain places. Dont some places just plug ur car into some system and if u got the o2 sim it'll pass?

Yea I think some states just hook your car up and make sure there are no codes.
