I've decided to not cut my cat, got pulled over by the Oklahoma Highway Patrol. They considered it too loud and had to run a sniffer to see if I had a cat. No ticket thankfully, mainly because I guess the only thing that made my exhaust legal was the dumped tips were long enough. So looks like I wont cut it. Next thing on the grocery list is to either throw a 351's 5 speed in it, flatbed, or to put off-road lights with a brush guard or headache rack.

Good choice, if they didn't serve a purpose they wouldn't be there. If you want more noise without losing the practicality you could always replace them with high flow cats, though the factory ones get pretty good flow anyway.

Holly crap. People have been swearing up and down that this could never happen. I'm glad to see someone can finally attest to it. It will happen more often. Politically our trucks are not popular. People of influence in politics are wealthy and see no reason to keep our trucks on the road. Even the ones that like classics think mainly of trailer queens. The biggest supporters of junker laws however are not tree hugging hippies, its the automobile industry. The more old cars are taken off the street the more new ones they sell. There is not a state, county, city or town that doesn't have some auto industry in it that would love to increase business by outlawing old cars. So its up to us to keep ahead of them and keep our trucks on the street. If they can convince enough voters and politicians that all these old trucks make smog they will be able to pass laws that simply make it impossible to drive them. Don't give the system any more ammo.

I've heard from a few mechanics that "high flow" cats really don't do anything. Companys just say it to say it. But I like your idea to not take it out, especially if you already got pulled over for noise. Good luck with what else you put in it!

Using a high flow cat as a direct fit replacement does little to nothing, they just have a little less density on the inside. A lot of people use them when changing exhaust sizes. For the most part stock converters still allow decent-good airflow so it's pointless to replace unless it's faulty. But if you bump up to a 3 inch exhaust a high flow does the trick nicely.
