Royal Exhaust offers a full line of supreme engine-to-tailpipe coverage of replacement exhaust systems and components for popular domestic and import cars and trucks. We realize repairs for your vehicle can be costly. Royal Exhaust has become a trusted and reputable name in the internet because of our competitive prices and excellence customer service. Royal Exhaust Direct-Fit Catalytic Converters are designed for easy bolt-on installation by a Professional Installer. Each product is designed to match the original equipment specifications. While the majority of our products do not require welding, cutting or bending, limited applications may require additional welding for optimal installation. Please Note: We are fabricators. Some converter applications may require the re-use or replacement of OEM gaskets. Please allow 24-48 hours for support to respond to your questions. Royal Exhaust warranties all its converters with 5 years of warranties with proper paperwork (Pre-assigned RGA#) and an online form completed in advance. The RGA # should be clearly mentioned on the outside of the return package on a tag or a label or legibly handwritten. The product has welding problems at the joins and is not properly welded sealed, thus causing leaks and is dysfunctional. A spot welding issue which is not able to hold the heat shield covering to the main converter and therefore is letting heat leak out. Dysfunctionality in the product which was not caused by impact or abuse. A failure in the product due to a hole caused by rusting rendering it unusable. When a converter is attached to an engine due to “Check engine Light” coming online and a new converter cannot solve the problem, it means that maybe the converter was not the cause of the problem in the first place. The internals of my catalytic converter have melted down after a few months of it being installed on my vehicle. Was my converter faulty from the factory? Converter meltdown is primarily contributed to an engine misfire. The unused air and fuel resulting from an engine misfire will cause an intense fire inside the catalytic converter damaging it internally. Normal operating temperatures of a converter are 500-800° F, and up to 1200° F when the vehicle is under heavy load. To melt the catalytic converter’s substrate, the temperature inside the converter would have to exceed 2000° F. Will replacing my converter with a new one eliminates the P0420/P0430 code from coming on? There is no guarantee that replacing the converter will keep a fault code from coming back. If an engine performance issues exist, and it has not been repaired, the P0420/P0430 fault code may recur. Why did my converter fail? Typically, converter failures fall in to one of the following categories. Physical damage due to corrosion, or from the converter contacting a large object on the road surface. Contamination – due to excessive oil consumption, internal coolant leak, or excessive carbon build up. Melted substrate – due to engine misfires which lead to excessive converter temperatures. Thermo quenching – hot converter is cold quenched when driving through deep water or into deep snow. Converter aging/lack of engine maintenance – cycles of damaging engine conditions will eventually deteriorate converter performance. Why is my “Check Engine” or “MIL” light indicating that I have a “P0420 “Low Converter Efficiency code; does this mean the converter needs to be replaced? A P0420 low efficiency code does not always indicate that the converter needs to be replaced. On newer vehicles a low efficiency code will can occur if the exhaust feed gases are not of the proper balanced to allow the converter to operate efficiently. An experienced emissions technician may be able to identify and resolve this concern with a scan tool, the most effective way for most technicians to diagnose this condition is using a 5-gas analyzer. Are there any steps my technician can take to prevent my new converter from failing prematurely? Since converters are designed to last the life of the vehicle the technician should identify and correct the root cause of the original converter failure. The technician should make sure any other codes are corrected prior to installing the new converter. This is especially true for misfire, mass air flow, rich/ lean conditions, and O2 response rate codes. Pressure check the cooling system to test for leaks which will contaminate the new converter. Repair any exhaust leak that may be present. An exhaust leak may affect converter and O2 sensor operation. Check O2 operation: The front sensor should have good frequency, amplitude, and response rate and average 450mv. The rear should be fairly steady at idle and above 450mv (typically 650-850mv). If both above O2 sensor readings are not present, the vehicle should be checked with a 4 or 5 gas analyzer and repairs should be performed. How do I determine if I have a California emissions vehicle? To determine if a vehicle has California emissions, check the emissions sticker on the vehicle, which is in the engine compartment. If the sticker states the vehicle meets California requirements, then the vehicle is equipped with California emissions. Is there a dimensional difference between a 49-state legal converter which shows Federal or California options? Vehicles licensed outside of California, but built to California emissions standards, may have a physical difference from a vehicle built to Federal emissions standards. (If your vehicle is manufactured to California emissions standards, it cannot use a converter that is cataloged as Federal only). You need to reference your vehicles emissions sticker before purchasing a Walker converter. A vehicle licensed in the State of California must use a CARB approved converter.
