Looking for thoughts on wide band placement. I want to place it on the collector so i can drill out the hole and have a muffler shop weld in the bung. This places the sensor at about 9 or 10 o'clock. I see most installs on here between the cat and the collector but the factory o2 is on the collector...can't be that bad right? I mainly want to this because the car is down waiting for parts and i can start this side project. Otherwise i'll need to get the car running and drive to the muffler shop to place the location further downstream
