Hey guys
I replaced my cat with one made by flowmonster part # 610513. It was made just for our trucks. It was an easy weld install. with that, two new walker O2s, a flowmaster super 44 and all new pipe the truck sounds and runs better than it has in a long time. My gas mileage is also going up. I was running it before with a gutted cat but my low end suffered with the new cat it is peppy again. The converter is on ebay or on their site flowmonster.com
Has anyone else on here tired one of these converters?

 

Have you checked your plenum? That is the leading cause of failed cats on these trucks. If you haven't addressed that, your new cat may not live very long.

 

I have had it checked. They said it was good. Replaced the PVC valve and a while ago i looked in the throttlebody and its still clean. I gutted the cat cuz it was rattleing so much it didnt seem to be plugged though. I will continue to keep an eye on it it would suck to destroy a new cat. I got wires champion/mopar plugs and wires to install next. i have no misfire codes yet and i want to keep it that way. by the way the flowmonster cat was about 80$
