For safety and legal reasons, a faulty catalytic converter can’t be ignored. The catalytic converter does the job of transforming toxic gases into less harmful compounds and a malfunctioning converter could cause poor vehicle performance and/or a failed emissions test. If you need a direct fit catalytic converter, Walker has a wide range of direct replacements for OE converters that will require no modifications to install. Walker's parts fit like OE because Walker is the catalytic converter supplier to many vehicle manufacturers. Catalytic converters by Walker are designed with an ample precious metal loading to ensure the required reduction of emissions is achieved. They are constructed and manufactured to satisfy all EPA policy and emission control requirements.

The Exhaust Manifold with Integrated Catalytic Converter has thick OE-style flanges for greater strength and OE-style routing for straightforward installation. Hangers and sensor fittings are included if required by application. It features leading-edge washcoat technology to ensure premium performance. The catalytic converters that are not CARB (California Air Resource Board) compliant are backed by 25,000 miles catalytic performance and 5 years/50,000 miles structural integrity warranty. The catalytic converters that meet CARB regulations and are legal in California are covered by 5 years/50,000 miles catalytic performance and structural integrity warranty.

Walker® is the world's leading manufacturer of automotive exhaust systems and emission control products for the replacement and OE markets. It offers complete engine-to-tailpipe exhaust solutions and exploits modern emission control technologies that fully satisfy the needs of the automotive industry.

Limited Lifetime Warranty

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.

Tenneco's obligation under this warranty is limited to replacement of the worn-out or defective product with the same product in accordance with this warranty.

To make a claim under this warranty, return the worn-out or defective product with the dated original receipt to the dealer or retailer from whom it was purchased or to a Tenneco dealer for verification and exchange under this warranty.

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.

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.
