Need to replace the cats on your Jeep? This is a 2-piece set of direct-fit catalytic converters for the 2011-2012 Jeep Grand Cherokee with the 3.6L engine. The brand is First Choice Exhausts, part number DGDR01-02, and they're made in Canada. They feature a platinum substrate inside a stainless steel body for durability and efficiency. They come with bolts and seals for installation and have both pre and post-catalyst oxygen sensor locations. The fit is 100% accurate with a bolt-on connection, making replacement easier. They are EPA labeled, but important note: they are NOT legal for sale or use in California (CARB-compliant), Colorado, or New York on vehicles with California emissions. For New York, they can only go on federal emission vehicles. They weigh 22lbs, have an uncoated finish, and are not considered a performance part. If your check engine light is on for catalytic converter efficiency and you're in a state that allows it, this direct-fit set can solve your problem without needing a custom exhaust shop.
