Gutting a cat on 6.0L

[bigd4x4]

How hard is it? Is it just a matter of removing the cat and nocking out the center with a extention and hammer?

Or just buy a test pipe for about 50 bucks like I did and save the kitty in the garage so when you sell the truck you'll have it back on. You could sell the working kitty for a small profit if you don't use it later. Dealers are getting wiser and inspecting under them for working emissions and will deduct the cost of repairs from the value of the truck.

I was thinking gut becuase no one can tell it's been done (especially a overanxious inspection station). Were did you get your "test pipe"? just in case I decide to go that route.

I have done it without taking the cat off. Just take the tailpipe loose from the back of the cat and ram a rod in it to break the guts up. and for the best part, crank the truck, hammer the pedal and blow all of it out.

As federal mandates to eliminate CO2 in vehicle emissions get stiffer, tailpipe emissions testing will become common place...which means they will be measuring the Carbon Monoxide that a working cat converts to carbon dioxide. With a working cat, almost no carbon monoxide will exit the tailpipe (diesels produce small amounts to begin with). They already do this in some states so my opinion is if you gut the cat, you maybe buying a new one to be able to pass emissions testing in the very near future. And if you price these babies, you don't want to have to pay for a new one. I would get a cat delete pipe and save the old cat for future use.

I know I'm new here, but I've gutted & deleted my share of converters on my gas trucks/cars.

One thing I've learned was ALWAYS SAVE THE CAT! Just replace it with a pipe. If you have to sell the truck or get smogged again, it's a $50.00 problem.

If you gut it, and then have to get smogged, you're skrewed.

Alright you've sold me on the test pipe. Anyone know were to get a test pipe that will just bolt on to the stock exhaust like "Shadow Grey" 's pipe?

[Shadow_Grey]

It is a MBRP FS9414 Stainless Steel test pipe. The aluminuzed one is a FAL414. They say it only fits their exhaust but as you can see I have it on my stock exhaust pipes. NO MODIFICATIONS either. 15-20 minutes to put on.
