NOTE: This converter will fit for California & Federal Emissions Vehicles however, is NOT legal for sale or to be shipped to California or for use on vehicles licensed in California. 

NOTE: Before buying any catalytic converter, you must be aware that converters are designed to last the lifetime of a car or SUV/truck. If your converter needs to be replaced, it is due to an emissions error or a problem in your engine tuning. This must be corrected before you or the installer install this converter. STOP, LOOK, CHECK! Have this conversation with a qualified installer. Blue and overheated converters and their shipping are not covered under warranty. STOP, LOOK, CHECK! Look at your old converter. Is it BLUE? Converters that are blue from overheating or painted, cut, or modified in any way are not covered under any warranty.

NOTE: If your new or old converter is rattling inside this is caused by the ceramic brick inside being overheated and cracking. This will happen to the new converter you install, as well and within five minutes, if you have an emissions failure in the engine. This is not covered under any warranty. 

We recommend that you look at our item #221804448055. This product may turn off your PO420 Code, if your converter can be saved. We also recommend buying this kit before changing your converter. These items are specially designed solutions to remove excess carbon & soot. For Catalytic Converter Efficiency and long life we recommend the use of Top Tier Fuels and regular fuel system treatment every 5,000 miles. We also recommend a professional de-carbonizing when replacing a Catalytic Converter or every 80,000 miles. This Converter can NOT be shipped or sold to the state of California. In New York, it can be sold for installation by you, a private individual as the installer. Please consult your NY- Registered Repair shop before buying this converter. 

These converters are equipped with more surface area which means better performance and quality. They have more Platinum and Cerium. Cerium absorbs oxygen, which promotes cleaner burning, that is also important in triggering the engine light on more sensitive OBD II systems. They do not require cutting, sliding, clamping, or welding for installation.
Direct fitting flanges and air tube connections make our product fit more like OEM than any other which results in less returns and a more satisfied installer.
