I think my secondary has a sensor coming out of it? ISTR a "fix" that involved pushing this sensor a couple inches out of the exhaust stream to clear a cat code?Since the secondaries dont really have any effect on codes , if they are in good shape you can leave them, or hollow them out.
The secondary has the port for the sensor, but it's on the straight pipe section before the catalyst material, so its really just reading what's coming out of the primary. Nothing reads what's coming out of the secondary so it's not "monitored" by a sensor.I think my secondary has a sensor coming out of it?
