my truck is a 94 3500 dually. 6.5 turbo. F code. no O2 sensor or egr. my question is, does it have a cat converter on it? looks like one behind the trans crossmember but not sure if its a cat or just some type of chamber.

 

cut it off

 

I'm sure that its probably a cat. There is an easy fix for that tho cut it out and put a pipe in its place. Plus you'll get better flow too!

 

well the cat or stoop trap sat right behind trans crossmember the F code did not used 02 or egr fcodes where only in the 3500's

 

i dont have the pipe to put in its place, so i took it off and punched it out. nothing left inside it now. will this do any good for it?

 

Its a soot trap. That should help flow.

 

mine was plugged i would cut it off

 

took care of it. thanks to all who replied
