So I’m only briefed on the matter as I watched that smeedia video on YouTube and he mentioned O2 sensors and catalytic converters are affected since they relate to emissions regulation.
I take that to mean it does not matter what aftermarket j-pipe I buy, they all are going to be incompatible to tune with a cobb accessport. Am I understanding that correctly? Unless, the aftermarket has two cats like the stock ‘15 WRX j-pipe and the exact same amount of O2 sensors?
