    For safety and legal reasons, a faulty catalytic converter can’t be ignored. By transforming toxic gases into less harmful compounds, the catalytic converter does the important job of limiting emissions. If you are looking for a quality universal fit catalytic converter, you can rely on Walker as it has vast experience in manufacturing emission control devices. Walker produced crankcase emissions control equipment in the early 1960s and, working closely with the Environmental Protection Agency (EPA), produced the 1st universal aftermarket catalytic converter in 1978.

    Unlike the direct fit catalytic converters that come ready to install and are designed to fit your specific make and model with no alterations, the universal fit catalytic converters may require cutting, welding, and other modifications to complete installation.

    Walker warrants qualifying exhaust products against defects and wear out when used on private passenger cars and light trucks under normal operating conditions for as long as such original purchaser owns the vehicle on which they were originally installed.

    This warranty gives you specific legal rights, and you may also have other rights, which vary from state to state. Any implied warranties you may have under state law are limited to the same duration as this warranty. Some states do not allow limitations on how long an implied warranty lasts or do not allow the exclusion or limitation of incidental or consequential damages, so the above limitations and exclusion may not apply to you.
