Review on PARTS DIYER Catalytic Converter 1999 2007 Chevrolet by Jose Ballard

This product was easy to install but never worked. I tuned and serviced my truck before replacing the converters and oxygen sensors. Heck, more work, even the replaced BCM still has Cats performance codes below threshold. Here's what he read before I replaced them and after the $1,000 makeover plus new cats. In two different workshops they told me that the cats are bad, the oxygen sensors are working fine. It is recommended to exchange the cats again. With a limited income so I bought them for starters. Everything the seller told me to do to fix the P0420 was done before I replaced the cats. Stuck with a truck that doesn't pass emissions and can't afford to replace the cats again.
