04' 6.0L Cat delete?

[firemedic355]

I know there's probably 100 threads on this but I can't manage to find any right off.

I recently got a 2004 F-250 with the 6.0L after selling my 7.3L. I did a 4" turbo back on the 7.3L, but it didn't come with a catalytic converter. I know plenty of people delete the cats on these new ones, but I live in Colorado and have to do diesel emissions testing. Can I delete the cat and still pass emissions? And will there be any negative effects on exhaust like engine codes?

Thanks for any advice

You might pass emissions w/o a cat but you will fail the "visual" inspection. I'd suggest getting a TB exhaust with a "cat delete" option where you can run w or w/o a cat. Then you can run your truck catless until it's time for inspection, then throw the stock cat back into the system for the day.

You won't get any codes, as far as passing emissions I can't help you out on that. We don't have that here in Indiana. I will say that if you delete it you won't be sorry. You could take the cat out and have it fixed so if you had to you could put it on for testing but not sure how much trouble you want to go through.

Yeah, I had considering doing just that so I'm covered either way. I can get some really good deals on systems that keep the cat if I can just find someone to sell me a cat delete pipe at a good price. Any idea what those cost by themselves?

[07OUTLAW]

MBRP cat delete pipe's aren't too bad, $50-70, maybe cheaper, depends where you look and what kind of deal you can find.

I'm not sure if their delete pipe will work with exhaust systems besides their own

I heard an 04 this weekend with a muffler delete and cat delete.... sounds awesome. Even on the stock exhaust system he had with the deletes, it sounded better than most chevy's I've heard, including those with 5" straight pipe. It blew my mind. I know the next thing I'm ordering... exhaust!

This is where I got mine at, saved my cat just in case I needed it down the road.

i'd recommend NOT drilling out the CAT, cuz you never know when you might need a legit CAT. I got a CAT delete pipe, it takes less than 1 hour to swap them out. The CAT delete cost less than $100, the CAT probably cost 5x's that. With the CAT delete and the thru muffler, the turbo whistle sounds awesome!
