Ok, about to pull the trigger on a PCV with Auto Tune. Curious about the location of the O2 Sensor. I know the stock location is in the right side muffler. I'm considering putting it right after where the exhaust manifolds join. That way if/when i install slip-ons I won't have any issue with having to put a bung in the new slip-on. Has anyone done this? Any issues? Is there a pic available showing it?
