Here's my sticker on the bottom of my hood near the latch. ('01 F350)

As you can see in the lower left corner, it says "Non-Catalyst." Look to see if your Mom's Ex has this sticker.

 

Thank You, GD.

That linked thread is only a few months ago, I usually remember and will look for recent discussions. Sorry.

I went and looked again. I found the pink sticker on the passenger valve cover, under the fresh air pipe. I cleaned it, and there is no "OC". It looks just like the pink sticker in Z-MANN's post above.

Thanks again.

 

no worries at all.
Sorry I couldn't be more help.

Would you mind posting a pic of your valve cover sticker?
It would help the next guy.

You were plenty of help. I found it because you helped me figure out where to look.

I knew I should have taken a pic when the charge air pipe was off to gain access to the sticker to clean it. These will at least help to know where to look for it. As I said, it is identical to the pink sticker in ZMANN's link.

 

never had to deal with any testing (surprised communist Illinois is missing out on that $) what if your VC doesn't have stickers?

 

Oh don't curse us yet.... one day they'll come for our straight pipes... Let us take our time😂

To add to the conversation... I can't find my sticker on my '03 at all. I probably need to remove the insulation on the hood to find it but haven't had the guts to do it yet.

 

I'm at my place in Tucson writing this Friday evening. Drove over this morning from Los Angeles 505 miles with no drama or hickups. The way it always is with this truck.

It passed emissions no problems, the guy didn't even look at the sticker. Oh well.

Thanks for the help and interest.
Cheers
