anyone done a cat delete on a 6.2?

In the past I have always chopped the cats on my 460's and gutted them on my cummins.

Has anyone done a delete on a 6.2 super duty? I have seen off road pies on thr Raptor 6.2's

It's my way of letting people know I'm subscribed to this thread

For whatever reason you would even WANT to remove the cats from a brand-new truck and void your warranty, and the obvious problems you need to work around in terms of the "aft" O2 sensors and the catalyst monitors in the PCM, this is sure to generate some controversy.

If you really want your exhaust to smell, or to poison yourself and/or your family with carbon monoxide, go right ahead.

Let the party begin...

My 2011 F250 6.2 just came off warranty(at 80,000 kms because it has an over 8400 kg gvw ?????) and the cat is plugged.NO WARRANTY.I am not happy.Will not spend the $2500.00 they want to put on new one.PO420 AND PO430 CODE COMES EVERY TIME I fill up.Tech thinks valve in fuel tank is flooding engine when I fill, causing the exess in cat.I hope there is a way to bypass this.If anyone has an answer I would be grateful.

I pulled my cats off. I have the 5 star tune so It doesnt throw a code.
I woud have left themoff but the tuck sounded horrible. Tey were only off the truck for about a 1/2 mile and they went back on.

I cant emphasize how bad the exhaust sounds without the cat.
In the past I would pull the cats off of my 460's. the exhaust would get a deaper more throuty sound. the 6.2 sounds like *** with the stock muffler and no cats.

I woul look towards the Raptor forums. a lot of the Raptor guys are running 6.2l with no cats, lomgtubes and a performance exhaust

Ordered from Mike at 5 star,looking forward to better performance.The funny sounding exhaust will be better than the sound of $2,500.00 going out for new cat!!!

We don't go through the smog checks here,and to update,ordered a programer from Mike at 5 star.Had cats taken off,truck is louder,but o.k.Noticed better fuel figures right away,but that is probably the lack of restriction.I am really looking forward to see what the new program will do.Will keep you all posted.

Just an update,mileage is up about one mile per gallon over all,maybe a little more.Sounds good to me out the exhaust too.I am really impressed when I use 91 octaine, as it drives and runs so good on 87 performance,and I have to check the mileage again,but think it is about one and a half better.
