I am ready to put some headers and true duals on my ss and was wondering about emmisions. I have no emmission restrictions in Illinois and was wondering about not running cats. how much are new 02 sensors? Also is there any good dual set ups out there. thanks

 

dont know the answeres to the other questions, but i got new 02's for 130 from gm, 2 of them to a box

 

i live in central illinois and i am running LTs and and ORY. since you have no emissions testing, its up to you as far as running without cats.
