Cat converter delema

[JeffsJeep04]

With their value on the scrap market, I'm a little hesitant to cut it out and gut it, when I can bring it in whole and get a chunk of change. I'm assuming diesel cats are worth the big bucks too? Anyone brought theirs in for scrap? What's the factory pipe size, 2.75"? I may just get a test pipe to weld in to hold me until I can do the exhaust, but with 180k and counting on the factory cat, I'm sure it's plugged about solid.

Ours are worthless, they contain no precious metals. They are not even cat converters, they are merely a soot trap... aka a metal filter.

IM surprised your Vin "F" truck has a cat on the exhaust.

 

[JeffsJeep04]

Ah, well, that solves that then...out comes the big screw driver She's definitely got one though, I've heard all the post 92(?) trucks had them until the duramax came out.

I haven't forgotten about you either, I just keep forgetting to grab that cover in the mornings...lol.

took mine out for the 5" turbo back system and only got $35 for the cat, guy said if it were a gasser cat and for the size it woulda been like $250

IIRC, only 99 model does not have Cat, may be late 98.

My 98 has, ugh umm, had a cat. I took it off and thought about scraping it, after reading this I'm glad I didn't. I thought it was wierd that I had a "F" engine with no emissions but still had a cat.

My 1999 Suburban had a cat but it went missing.:rolleyes5:
It is an F-code

I think the internals of mine are going to go AWOL this weekend. 2.75" pipe is tough to find apparently...

 

[dur0maxx]

Take a 3" pipe and it will slide right over the stock pipe. Probably not the best but that is what I had layin around and it slide over perfectly. Ran a bead around it an no leaks yet.

I took mine in and they gave me "large cat" price for it. i think it was $100 or something like that. i told them that there wasn't any metal in it but he didn't care love the 4" i got now

My 2000 K3500 has one and it's an F. It is scheduled for catectomy soon.

Are you sure there is not platinum in the 6.5 cat's? Isn't it a 2way cat?

No precious metals in our kitty's puurrrrr........

certain.

Our cats literally just have a screen mesh in them...which is a joke if you ask me.

When I had my 6.5 I took the cat off because I thought it'd help reduce EGTs, it really didnt change that I could tell.

My 6.5 TD was a dump-truck.

 

[Turbine Doc]

Mite wanna save that cat, replacement cost is astronomical, I have 2 on shelf just in case I have to sell to somebody that lives where cat is required.

 

[North Maine]

Whats astronomical? a 3 inch cat can be had from SS for 140

My 92 has a sticker in the glove box about the cat, its been one for a long time.
