All Vibrant Performance exhaust bungs are made from the highest quality stainless and mild steel to ensure the utmost in quality for all professional aftermarket and O.E.M Exhaust projects. This Vibrant O2 Sensor Extension will not only pull the O2 sensor back just enough to help with a P0420 code but it's also adjustable! Many times you are getting a "420" code but you can see the sensors working and you can see the catalytic converter is still good, but the sensor needs to read just a bit less to not throw the code. This will also help cars that have a downpipe and allow you to have full adjustment on how much flow it gets.  Keep in mind that this is not a permanent fix in all cases and will not work in some cases and is not guaranteed to fix the problem.
