    So i believe one of my cats if clogged, because my post 02 sensor is getting a low signal. I replaced the sensor twice and the engine light still comes on. So I'm looking to replace both cats. What are some top end cats that will improve the performance of my truck compared to the stock cats.

    Magnaflow and Hedman both make good high-flow converters.

    If you're in a city that does not do emission testing it would be cool to take your cats out. If you get a tune with that you will get better gas mileage and more horse power.

    If you replace them, don't throw them away! Salvage yards/recyclers are paying up to 100 dollars or more for them.
