$75 in my pocket from local scrap yard is what I'll gain. Don't think it'll lose anything after talking to several local guys who have done it.

Seems like a waste of time to me. Your cat doesn't hurt for performance, and if you need the scrap money you bought the wrong kind of truck. It's also illegal, and if I was buying a truck missing its cat, I would wonder what else was *******ized, and not buy it. Just my .2 cents....

1. The exhaust pipe section of the cat is rusted out.
2. I never said I needed the money. I don't know were this came from??
3. I am the original owner and have no plans to sell.
I am just wondering how the performance would change without it. A new cat is around $400 and a straight cat delete pipe might be $100 - $150.

Only diffrence I had with my truck was the exhaust was a little louder, and the exhaust smelled really bad. It would make your eyes and nose burn if you got a good wiff. Driving around town with the windows down and stopped at a red light was bad. Finally I installed a Magna flow cat, and no more bad smelling exhaust. I didn't notice any performance changes.

I don't need the money either. Was a sarcastic remark about what's gained when deleting the cat. Pipe to weld in place is free, I have a length of pipe n local shop will expand it free to slip over existing pipe.
Around here, we don't have emissions testing, so no worries in that aspect.

I have a little Dynatech cat on my truck for the past few years. I paid $150 for it a while back.
If you want to get rid of the cat I wouldn't just use a straight pipe in place of the cat. I'd gut the cat, put a piece of straight pipe the entire length or the body weld everything together and then weld it into the system to make it look as stock as possible. You would have to do this yourself. Every exhaust shop in may area will not gut a cat or remove a cat without installing a new replacement. They will not install a used cat either. All three are against federal law.

Sorry I didn't mean to be sarcastic. Honestly I was speaking as a guy who has been there done that with catalytic converters.

i had it removed on my old F250, and the biggest difference i think, was the exhaust sound. it may have opened up a few extra HP on the top end.
we don't have emission testing in our area of Louisiana (Baton Rouge there is though). i ended up trading the truck for a Harley, and they guy i traded with was from Tx. about a week after we traded he contacted me asked if i still had the oem cat... i said no, i told him the exhaust set up before we traded and he inspected it upon trading as well.... well he said he was stuck having to buy an OEM cat from the dealer due to TX emissions laws.
honestly i think that was an attempt to make me fit the bill for the purchase/repair. even though he knew what he was getting from the start.
