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.

Good Product. Needs Slight Modifications

The first one came damaged. I imagine it was damaged in transit. The replacement wasn't flawless but it was good for the most part. Installation for 03 Mazda Protegé5 ( Should be the same for other vehicles only difference is bolt sizes needed may vary among the fit of the CAT.) This CAT (does not come with bottom 3 studs) therefore you will need to buy (4) 1.50 × 30mm Grade 10.9 bolts to stick through the bottom 3 holes. They will only go in one way which in this case it is from the bottom up. You will have to screw on the nuts from the top of the holes as you stick the bolts through from the bottom up. You can reuse the nuts from the old CAT. You also have to drill through the side ring to open it enough to fit the 4th bolt through it. Like most aftermarket parts you need to make some modifications in order for the part to fit/work.
