What leads me to this question is that I'm about to go on my second set of O2 sensor on my OEM SVTF Cat. Both times I smacked my header/cat flange while driving. My question is whether the locatations of the O2 sensors were modified on the CFM Cat such that they wouldn't want to occupy the same space as the transmission housing if the exhaust happens to get smacked again?
I bought my car new, never had this problem and the first and second time I messed up the sensors were both in the past month! I understand it's common but If I could prevent it...
