Gutted factory cat

I was thinking about trying my truck without the cat and was wondering if anybody had just gutted the factory cat, and if so, did they notice a mileage and/or EGT improvement?

I need to be able to put the cat back on mine when it's inspected, and the delete pipe for my exhaust requires you to cut the pipes, so there's no way of putting the cat back in when you need it. That's why I want to try the gutted factory cat.

Anybody have a defective factory cat they want to sell for cheap?

The delete pipe does not require any cutting. There is a 2 bolt flange on one end and a clamp on the other. There are plenty of us on here that switch back and forth when necessary.

Please don't gut your cat. Those things are so EXPENSIVE. And you don't know when you'll need it in the future! get a delete pipe.

I gutted mine on my 03 and blocked the EGR at the same time, I decided to gut it just in case the smog police here in TX think it should have one. When I did those two things I picked up 2 extra mpg so all in all I am happy with it, and the truck looks stock but has kinda of a deep sounding exhaust left the factory muffler on too, probably put a magnaflow muffler in its place down the road. I have had 4 PSD and this is my first 6.0 I have gutted the Cat or cutt it off on all of them and they all pick up a little when I have done it. Plus I love the sound. SOme people may have a differnet opininion though, just my .2 cents.

I don't have a flange on mine. The cat just bolts between the downpipe extension and the rest of the exhaust. The kit requires you to cut the flange off.

I have a Banks exhaust, and their delete pipe requires modifying the entire exhaust where the factory cat will no longer fit, hence why I want to try gutting another cat, not my factory one.

Another great invention from Banks! A new cat is $650. A real user friendly exhaust system is less money than that including cat and muffler delete pipes. If you ever need the cat you will be sorry, but it's not my dime.

Yeah, but read my earlier posts. I don't want to gut my cat. I want to buy a damaged/unwanted one from somebody and gut that one.

Banks has a reason for their delete pipe being designed that way. If you just installed a pipe in place of the cat, you'd have the 3.5 restriction since that's the size the cat is. Theirs makes you cut out the 3.5 inch piece and use their 4" delete pipe. At least that's what it sounded like from the explanation the banks rep gave me. I just wish they made a 3.5 inch one that would bolt in place of the factory cat.

What I really need is a 3.5 inch piece of 409 stainless steel pipe long enough to go where the cat is.
