Review on 🚗 Walker Exhaust Ultra EPA 53270 Direct Fit Catalytic Converter: Maximizing Performance and Environmentally-Friendly Exhaust Systems by Matthew Miles

This was the first time I took on an exhaust system myself. Chicago winters took a toll on my '96 Grand Marquis exhaust from front to back, including catalyst holes. My main concern with this job was fitness. Walker has been around for a long time and has one of the best reputations for straight fit replacement parts. I didn't mind any differences in transducer sizes on this unit as Walker would go broke if they didn't get the job done. I used all Walker parts on the rest of the system and the fit was almost factory with no modifications. These converters work well and I had no trouble passing the outlier test. Remember that if your car isn't working well, this should be fixed before replacing your converters, as a malfunctioning car can damage or ruin your new converter, causing unnecessary trouble and frustration.
