i was looking around at review of megan racing 4-2-1 headers for my ej8 and saw mixed opinions saying that they are not street legal. i live in illinois and im wondering if they are street legal or not. any help?
CARB Certified only applies to Californiaif it deletes and O2 in any way, or deletes your catalytic converter then i would said its probably not "carb certified" i.e. illegal.
