my 3.5 has had issues with throwing a P0430 - bank 2 (which I assume is still driver side) cat below efficiency threshold. Previously it would come and go and might go away for months. I did replace the driver side rear sensor, didnt matter. Now it's throwing the light almost as fast as I can clear it. From what I can gather there were a lot of issues with earlier cats. Truck seems to run ok for now but looks like it's time to do something about it.
Anyone used an aftermarket replacement they're happy with or should I buy another OE cat? You can get just the OE cat section on the driver side for $500ish I think. I wouldn't be opposed to a new downpipe but I do want cats, don't want the smell or extra V6 noise (turbo whistle is ok).
@Livernois Motorsports - you all have any input on this?
