    Product Details

    Ultra™ Catalytic Converter and Pipe Assembly (16799) by Walker®. Converter Configuration: Direct Fit. Position: Rear. Catalytic Converter Body Shape: Round. With Pre-Cat O2 Sensor Port. Catalytic Converter Overall Length: 27.75". Walker is an OE supplier to many major nameplate vehicle manufacturers. Trust Walker, an industry leader, for the finest emission control technologies for import and domestic vehicles. May require modifications to complete installation, professional installation recommended.

    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.

    No Box?
    Part is fine but not sure if it was dented when shipped or got dented on the way to us. But it wasn't in a box so it was dented. Got 2 parts both not in box and both dented.

    Fit
    It works as a replacement but the hanger is about 3 1/2 - 4 inches lower than the rubber hanger of my SUV. I had to use a wire from the pipe to the rubber hanger to support the pipe.

    Installation
    Exhaust system was of good quality except there was a whole pipe completely missing between the two catalytic converters.
