WARRANTY TERMS AND CONDITION

Royal Exhaust warranties all its converters with 5 years of warranties with proper paperwork (Pre-assigned RGA#) and an online form completed in advance. 

Please refer to this link: https://drive.google.com/file/d/14pr6fKPRRDr8SBRtlmOSKKccu6haQvt0/view?usp=sharing

The RGA # should be clearly mentioned on the outside of the return package on a tag or a label or legibly handwritten. For any returns the buyer will pay for any return fees incurred and a restocking fee of 20% of the product price will be charged. The returned products should be shipped back with a completed warranty form.  

  1. The product has welding problems at the joins and is not properly welded sealed, thus causing leaks and is dysfunctional. 
  2. 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. 
  3. A part that does not fit the vehicle due to incorrect bending, inlet/outlet flaring, incorrect flanges, and damage to the product caused in shipping. 
  4. Dysfunctionality in the product which was not caused by impact or abuse. If a converter has suffered damage from the impact which results into structural cracks or causes physical damage or breaks the product by any means, it is not the responsibility of the manufacturer and thus no credit or refund will be provided. 
  5. A failure in the product due to a hole caused by rusting rendering it unusable. This should have taken place during the warranty period to be eligible for a refund, for which documentation of the purchase should be available (Invoice and the warranty form filled out).
  6. Converters which are subject to excessive heat and shows the signs of them by getting discoloured and do not perform according to the standards described by the manufacturer, they are not defective but are damaged by an improperly functioning engine, which results in to expelling of unburned fuel and thus increasing the temperature of the converter resulting into its damage.
  7. 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.
  8. Documentation from a trained mechanic indicating the code number of the product, his expert diagnostics and the reason for return and repair must be included with returned converter to obtain credit along with the warranty form.
  9. The manufacturers liability is limited to the refund or the exchange of the product that was originally shipped to the customer according to their order. no different product as an exchange will be provided to the customer.

The following FAQ's might be able to helpful before you make your purchase


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?

No. 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?

Yes,

  • 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. Click Here for Engine Family Number Information.

 

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.
