O2 Bung Extender

Exhaust - O2 Bung Extender
Exhaust - O2 Bung Extender
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.

Solid Product

Great construction/welds. I purchased this to hopefully avoid a cel when switching to a catless DP. It has been a week, no cel
