So I live in an emissions county in Colorado. And I know several people will tell me to move but that's not an option. And I know people will tell me to move anyway. Still not an option.

I have a 1997 F250HD with the 7.3.

I need to pass a visual inspection and "opacity" test to get plates on my project truck. I'm not building my truck to roll coal so the opacity test is easy.

The visual inspection is the problem. The PO cut off the cat a long time before I bought the truck. I need one to pass inspection. There are no OEM cats available anywhere.

Does anyone have experience finding an aftermarket cat that will meet Colorado emissions standards?

Does anyone have an OEM cat laying around they'd be willing to ship me?

Thanks for the help.

I'm not sure if those will be kosher. CO requires basically CA standards. It need to be OEM or have a CARB EO number to pass inspection.

For the visual you could possibly just place a hollowed out muffler in front of the factory muffler and get away with it.

Did the previous owner also upgrade the size of the exhaust also?

Here is a picture of my factory cat that I am keeping just for the reason of possible emissions in the future.

The PO basically cut off the exhaust after the down pipe and 90° turn under the cab. So I'm going to need some parts regardless.

All of the exhaust kits I'm finding want to keep the factory cat.

Have you though of going to a exhaust shop and seeing what they can do for you?

They haven't gotten back to me. But I have a couple of options there.

May of found you a source for your cat depending on the member. He just joined up and said that he is thinking of straight piping his truck.

Upgrading 96 7.3 injectors from stock.

Hi, I am new to the group and seeking some guidance and intuition on finding the right fit in aftermarket injectors. While I am probably asking a fairly common question I'd like to get some input from the experienced. Anyways, I have a 96 f350 7.3 4x4 A/T which I received from a family member...

I just tossed one in the trash a week ago 🤦‍♂️🤦‍♂️🤦‍♂️ I am fortunate and live in a no emission county in Colorado.

Bad timing.

I have to be here for a job so moving to a non emissions area isn't an option for a while.

Yeah, Colorado follows California emissions standards now. I can chance it and maybe sneak by. But I'd prefer a stock cat mostly because no one makes an aftermarket cat with an EO number.

Thing is, it can be completely gutted. They don't check that. As long as it blows clean and passes visual I'm good. It's stupid.

Hope you are able to find a stock one or aftermarket that fits your needs. I’ve always gutted the kitties on my trucks (and use as a resonator), it takes the harsh exhaust tone away. Usually removed the muffler too and place exhaust in stock location. Years ago someone on here did extensive Dyno testing and the full stock exhaust (with round DP and gutted cat, stock muffler was good for 405 rear wheel hp. Above that HP level aftermarket 4” exhaust made a difference.
