I've searched and read through the threads about MA emissions. Does anyone have any updates?
It seems that even if I had a catted downpipe (considering buying the CTS Turbo catted downpipe + Borla catback), I would still fail emissions unless I put an 42DraftDesigns O2 sensor "spacer" to the O2 sensor closest to the catalytic converter.
Even with above, do I still have to revert the ECU back to stock in order to pass emissions? Or can I keep it in the tuned position?
It seems that to have any reasonable power gains, we really need to get a downpipe since the stock catback exhaust is good enough (except that it doesn't sound as nice as an aftermarket one).
Thanks in advance!
