More questions have come up
Right in the middle of my downpipe and FMIC install and about to go with the MHD tune. Thinking of stage2. Do I need to change my spark plugs for colder ones or will I be OK with the OEM ones?
And, will I get a SES light after the removal of the downpipe CATS? I do have the O2 sensors in their respective places. Went with the VRSF downpipes.
Thans for your input
