Catalytic Converter - Universal
1A Auto universal fit catalytic converters are made from high quality 409 Grade stainless steel. Our catalytic converters are designed and warranted by the manufacturer to meet Federal Environmental Protection Agency requirements for 25,000 miles. They also carry a limited manufacturers warranty against defects in material or workmanship for 5 Years or 50,000 miles whichever comes first.
1A Auto sells both direct fit and universal catalytic converters. The actual catalytic converters on both universal and direct fit converters are the same. Direct fit converters have pipes and flanges for direct bolt-in fit, while universal converters are just the converter themselves and will require welding or custom work to install.
Why do Catalytic Converters need to be replaced?
IMPROPERLY TUNED ENGINE: A number of problems could occur to as the result of an engine that is out of tune. Any time an engine is operating outside proper specifications, unnecessary wear and damage may be caused to the catalytic converter as well as the engine itself. The damage is often the result of an incorrect air/fuel mixture, incorrect timing, or misfiring spark plugs. Any of these conditions could lead to a catalytic converter failure or worse.
EXCESS FUEL ENTERING EXHAUST: The fuel that powers your vehicle is meant to burn in the combustion chamber only. Any fuel that leaves the combustion chamber unburned will enter the exhaust system and ignite when it reaches the catalytic converter. This can super-heat the converter far above normal operating conditions, and cause a melt down. Possible causes are an incorrect fuel mixture, incorrect timing, corroded spark plugs, a faulty oxygen sensor, sticking float, faulty fuel injector or a malfunctioning check valve.
OIL OR ANTI FREEZE ENTERING THE EXHAUST: Oil or antifreeze entering the exhaust system can block the air passages by creating a heavy carbon soot that coats the ceramic catalyst. These heavy carbon deposits create two problems. First, the carbon deposits prevent the catalytic converter from reducing harmful emission in the exhaust flow. Second, the carbon deposits clog the pores in the ceramic catalyst and block exhaust flow, increasing backpressure and causing heat and exhaust to back up into the engine compartment. Your engine may actually draw burnt exhaust gasses back into the combustion chamber and dilute the efficiency of the next burn cycle. The result is a loss of power and over-heated engine components. Possible causes are worn piston rings, faulty valve seals, failed gaskets or warped engine components.
DETERIORATED SPARK PLUGS OR SPARK PLUG WIRES: Spark plugs that don't fire or misfire cause unburned fuel to enter the exhaust system. The unburned fuel ignites inside the converter and could result in a partial or complete melt down of the ceramic catalyst. Spark plugs and spark plug wires should be checked regularly and replaced if damaged or if wires are worn or cracked.
OXYGEN SENSOR NOT FUNCTIONING PROPERLY: Oxygen sensor failure can lead to incorrect readings of exhaust gasses. The faulty sensor can cause a too-rich or too-lean condition. Too rich and the catalyst can melt down. Too lean and the converter is unable to convert the hydrocarbons into safe elements and may not pass a state inspection.
ROAD DAMAGE OR BROKEN HANGERS: The ceramic catalyst inside a catalytic converter is made from a lightweight, thin-walled, fragile material. It is protected by a dense, insulating mat. This mat holds the catalyst in place and provides moderate protection against damage. However, rock or road debris striking the converter or broken exhaust system support can cause a catalyst fracture. Once the ceramic catalyst is fractured, the broken pieces become loose and rattle around and break up into smaller pieces. Flow is interrupted and back pressure in the exhaust system increases. This leads to heat build up and loss of power. Possible causes of a catalyst fracture include road debris striking the converter, loose or broken hangers, potholes or off-road driving.
