Hey mate love the sound,I wanna get empire peformace headers for a 2003 impreza ,on your ones did the o2 sensors reach the new headers after installation or did you have to get longer o2 sensors cords

[@TheNodle]

hey mate, thankyou. I havent had the car for a while now, but i didn't change any o2 sensor chords. Although i think empire have updated their design

[@Noahmessina]

@@TheNodle okay thanks

[@azenxr6556]

Hey, do stock headers have cats connected to them or do they bolt onto cats

[@TheNodle]

dont remember mate, but it never threw a CEL after changing header. I would say the cat is after the header
