Hey guys,
I'm going to a catted x pipe from my pypes off-road x pipe (running longtubes) .I'm currently with a lund tune and I requested a tune revision for this and lund told me that unless I was running the car in a strict emissions state then a tune revision is not needed. I thought I would have to turn the rear o2's on right?
Thanks in advance,
