Re: CAT Converter

No problems. No need to tune anything. Only issue is if you had to get emissions tested.

Re: CAT Converter

welcome to PSN. cats and 02 sensors are a commiefornia emissions thing. my 02 here on the east coast does not have any of that crap.

Re: CAT Converter

My 01 did. My guess is you have a standard or a commiefornia truck.

Re: CAT Converter

thanks for responding folks. I got this F 350 IN connecticut. Truck was MFG. IN 02/98 EARLY MODEL. SO, check engine lights or O2 ISSUES will not be an issue?

Re: CAT Converter

you have to look at the under hood engine emission tag to see if it is a commifornia compliant truck or not. i have seen quite a few here on hte east coast that were driven across country and then sold here.

Re: CAT Converter

my 99 and my 97 both had cat converters from the factory, I live in Denver metro area with California style emissions laws so I must keep the cat on both of those trucks. Diesel testing is once a year here, what a huge worthless pain in the ass backasswards state this has become. Anywho they also want the cat welded in, no clamps...trying to keep you from making a "test pipe" just for the once a year testing.
The computer on your truck has no idea there is a cat converter, we do not have 02 sensors like a gas engine. If you do not have emissions DITCH THE CAT its only robbing you of power and MPG

When you remove your stock cat you may be able to sell it, I am not sure. Some of them are full or platinum and palladium so the cat converters can be worth some good $$$. When I recently removed the one from my 97 I was surprised to see it is hollow...no precious metals in mine. I replaced it with a huge dodge 4" unit so I am emissions legal..... as far as they know, once a year.
The superduty will say on a big sticker under the hood if the truck has a cat or is a non cat truck...... my 97 has cat, my 99 has cat, my 01 has no cat.... fun!
Huge waste of taxpayers money!!! The emissions program in Denver is a JOKE and has been for YEARS
Now CU Boulder just released a study.... "Diesels are polluting far worse then we originally thought".... when a Prius or a Tesla has a larger carbon footprint then a diesel Excursion...this place is so back ass wards I WANT OUT!!!!!

/Rant


Pull your cat when you install new exhaust, see if its full of a grey honeycomb material if it is = sell that SOB (you can take it to metal recycle yard and get $$$)
