Cat for a 5 or 4 inch?

[george]

Does anyone know if there is a cat or even a cat look alike for a 5" or 4" exhaust?

in the last issue of truckin magazine i got, there was a section on new SEMA products, and there was a magnaflow ad there that said they have high performance diesel cats now in 3. 5", 4" and 5"



the 600/610 series engines in the 3rd gen's also get a 4" cat...

The shell is stainless steel. A 4" or 5" end can be welded to it. The earlier cats had 3" inlet and 4" outlet.

Hey Joe

I have a truck that looks a lot like Sickly but it's a 96, it has 5" with no cat. I was just curious and kinda planning ahead in case I needed to have one on due to smog testing. It passed last year, the first year of testing, I'm thinking they may get more strict as far as the visual inspection as time goes on and they figure out which rigs should have what on them.
