This may be a stupid question, but while I was under the truck I saw this and had no idea what it was. Can someone help me out?

 

Which truck is it on? It looks like a 2nd gen cat.

 

Sorry, its on the 98. The truck came out of Montana, I didn't think it would have a cat.

 

12 Valve, that would be the cat.

 

Great, thanks for the help.

 

Emissions sticker on the rad support when you pop the hood will indicate if it is catalyst or non catalyst but as Mc mentioned, that is a cat.....all 12v CTD's manufactured after Jan. 1/94 were factory equipped with a cat.....98 and on 2nd gens w/24v replaced the cat with a resonator.

 

Nice drive line too.

Yeah, isn't that great!

 

Hmm , mine had one like that too. Must have fallen off in my travels. I'll have to replace.

 

My truck has one too. (But not for long) But on the sticker on the rad suport does not say catalyst. I even have that UGLY black pipe going accross the top of my valve cover too.

 

Thats probably the EGR required on California diesels?

Yes I know but my sticker does not say it is a catalyst.

 

To bad you are so far away, I would like to get my hair cut in a ctd. (nice drive shaft)

 

I have the same thing it is a cat,I going to cut it off because it could get cloged and effect your mpg.
