This will reduce the chance of getting a CEL for running a high flow cat in your car. It is made from Stainless steel, has straight and a 90 degree bend so you have two options for a more indirect flow of exhaust gasses to the rear o2 sensor. The 90 degree extender angle is adjustable so it can fit in any position.
We do not recommend running without the rear o2 sensor because it could run the rear o2 test and reduce your gas mileage.

Solved CEL

I'm running the high flow cat and i would get CEL every 500 miles. We are now at 3k miles and no CEL :)

No clearance

The new exhaust I installed was causing the 02 sensor to hit the heatshield. This did exactly what I was hoping it would in moving it out of the way.
