Hey guys,
I decided on the flowmaster catback and carsound catalytic converter for my 3.4 V6 with 2.5 in and out. Would the 2.5 converter attach to our stock headers fine (are the headers 2.5 as well)? Also, I was wondering if these products would pass California emissions and if so would I order the converter without the air tube because of O2 sensors? Any information about the sensors would be appreciated! I did a search on this topic, however it mostly just confused me. Thanks!
