Universal O2 Sensor Spacer Adapter Isolator Extender


The most restrictive part of any exhaust system is the catalytic converter. The stock catalytic converter is meant to filter the flow of exhaust gases to reduce the amount of harmful gases into the atmosphere. Because of this, lots of potential performance is restrained. High Flow Test Pipes eliminate the stock catalytic converter and reduce exhaust backpressure. The result brings out the vehicle's performance potential by giving it a free high flowing exhaust system. However, after deleting the catalytic converter on a OBD2 Vehicle, you'll end up with a P0420 Check Engine Light. This Adjustable O2 Defouler will fix that issue. Install in between the Post Cat Sensor and the exhaust and this, when properly adjusted using the 3 different inserts will keep that code off.
