More Information You May Would Like To Know

About Check Engine Light On
- Most vehicle owners care about if this catalytic converter can eliminate the check engine light on caused by code P0420 - catalyst system efficiency below threshold.
- We would answer definitely YES! But before replacing a catalytic converter, please make sure your O2 sensors still work well. Faulty sensors can cause damage to spark plugs, catalytic converters, and damage your fuel economy.

Replacement Guide (Do It Yourself)
- Raise the vehicle and secure it on jack stands.
- Identify the catalytic converter on the underside of the vehicle.
- Remove the oxygen sensors.
- Spray penetrating oil on the exhaust flange hardware and flanges, then remove the Old Catalytic Converter.
- Install new catalytic converter, direct bolts to existing exhaust system - Do not forget to install gaskets to prevent exhaust leaks.

High Flow Cats Increase Power
- The problem with regular catalytic converters is that they don’t always allow the gasses to pass through as efficiently as possible.
- High flow catalytic converters allow for the more efficient flow of exhaust gasses, removing restrictions that can impede performance.
- If the original OE converter does not match your engine power, a high flow cat might be a great choice.
