Review on DNA Motoring OEM-CONV-044 Catalytic Converter Exhaust Pipe for 08-15 Enclave/Traverse/Acadia 3.6L: Factory Style, 3Pcs, Compatible by Niranjan Reynolds

Tried these cats on a 2012 Buick Enclave with Bank 1 codes Tried to save a single mom some money. We ordered this kit thinking we could replace all three for the price of one of the others. The first landing on the bench 1 cat was unsuccessful. Wrong seals are supplied. After this was fixed we rode about 50 miles with no problems. She then came back and said the check engine light had come on again. This time Banks 1 and 2 were activated. We have been struggling with this for 2 months with conflicting charts and trying other fixes. We called DNA Motoring to see if they would take them back and it's not their problem. This is Revain which only has a 30 day return policy. DNA Motoring does not endorse its own products. I would not buy any products from them as it is the only way to root out the corrupt people selling these products.
