WALKER CATALYTIC CONVERTERS
Walker offers catalytic converters manufactured with a stainless-steel body, aluminized pipe and heat shields, that provide you peace-of-mind with assured compliance by engineers who set the standard. Whether it’s universal or direct-fit, catalytic converters feature an optimal high-technology washcoat and OE-design precious metal load that deliver required reduction in tailpipe emissions to match vehicle application. When selecting which catalytic converter is best for your vehicle, consult your state’s aftermarket converter regulations.
FIVE CHECKS BEFORE REPLACING A CATALYTIC CONVERTER
Converters don’t fail on their own, complete these five checks before replacing a catalytic converter:
- Retrieve / repair all PCM trouble codes, check for any available TSBs or PCM re-flash updates
- Repair all exhaust leaks
- Make sure vehicle is in proper fuel control
- Always check for internal coolant leaks and excessive oil consumption
- Make sure you have the right part for the application

WHY A CATALYTIC CONVERTER FAILSConverters don’t fail on their own; failure is usually a symptom of a larger problem. This is why it is important to identify the root cause of the failure and perform the repair prior to installing a new converter. Most catalytic converter failures fall under one of three categories:
|
DIRECT-FIT VS. UNIVERSAL CONVERTERSWalker universal fit catalytic converters have a customizable design with expandable bushings to adapt to connector pipes based on the repair. They may require specialized fabrication and welding for installation. Walker pre-bent routings hangers and flanges for OE-style direct-fit catalytic converters attach to the exhaust system for a direct-fit bolt-off, bolt-on solution. No matter what you select, all converters must meet the emission requirements of the vehicle and cannot be chosen by size alone. |
WHAT TO DO IF CHECK ENGINE LIGHT COMES ON?Troubleshoot an illuminated check engine light by making sure the gas and oil caps are on tight and that the oil dipstick is seated correctly. If the light remains lit, it could be triggered by a faulty oxygen sensor, failing catalytic converter, bad spark plugs, malfunctioning thermostat or bad mass air flow sensor. If the light remains on, make sure to make an appointment with your service provider as soon as possible. |
WHAT IS THE DIFFERENCE BETWEEN EPA AND CARB CONVERTERSEPA-compliant catalytic converters are for use on EPA or Federal emissions certified-vehicles. EPA-compliant catalytic converters cannot be sold or installed in California and Colorado and in certain circumstances in Maine and New York. In those states, you must install a CARB-compliant catalytic converter on CARB emissions certified vehicles in the states of California and Colorado, on all vehicles. CARB-compliant converters contain more catalyst material in order to converter emissions more efficiently and comply with stricter emissions reduction requirements. Check the vehicle’s emissions control information label and consult your state’s aftermarket converter regulations to select the right catalytic converter. |
Product Description
Designed to comply with EPA emissions requirements while delivering premium performance and durability with assured compliance, Walker® Ultra® Universal Catalytic Converters are available for import and domestic OBDII (1996 and newer) vehicles.

Now I've never had to do anything like this before so this was all new to me. I bought this item from the Amazon Warehouse for a discounted price which I thought would work out in the long run & it would have if I knew how to weld myself.
I ended up finding a guy to do my welding job for $150, better than all the shops I called & got quotes for. One shop tried to tell the would charge me $500 to cut the old one off & weld the new one on so I said heck no, & found someone on Agies List.
The money I spent in total, I coulve just bought a bolt on catalytic converter & saved myself the time because I ended up having to take the old one off myself & put it back on for the guy to charge me $150, it would've been a lot more if he had to do everything.
After the job was done, I cleared the codes out of the cpu with my obd2 reader, drove around for 20-30 minutes & was able to pass emissions, of course after all the computers were ready. 3-4 months later, I still have no issues so I say this was exactly what I needed.
I'm very pleased with the purchase or at least the outcome of the purchase. My only thing like I said was if I had known, I would've just bought the bolt on. You live & you learn so if I ever have to do anything like this again, I'll know what to do next time.
