Hi again. I am intending to fit headers to the Astra, ( Z22SE) and was wondering if others have done this. Using most of the original zorst, but removing the center resonator.
Has it affected the O2 sensor downstream from the Cat? If so, what remedies have people used to extinguish the MIL if it comes on?
Cheers
