I just got my 3" downpipe installed. ZZP forgot to send the 02 extension so the rear 02 is not attached at the moment and theres an 02 block (just a screw that goes in the 02 hole on the downpipe) in there right now. Do you think this will be OK for a week until I can get the 02 extension hooked up? My car hasn't thrown a SES light yet, but I'm sure it will soon.
