Default "USA Catalyst" on pipes
What does "USA Catalyst" stamped on one of the exhaust pipes mean? I purchased a set of headers and exhaust pipes for my 03 RK and was informed that they do not have a catalytic converter. But I noticed the USA Catalyst stamp.

2003 only CA models had CATs in them it appears you have a CA.
Set of pipes.
Latter HD moved them to the headers a much better place to put them.

I had a set of '06 catalyst mufflers. If you looked into the inlet end of the muffler with a flashlight you could see the gray honeycome catalytist material.

Just an FYI I was also able to core it out.

I can see the catalyst honeycomb material, but is that the same as a catalytic converter? The seller assured me that the pipes do not have the catalytic converter, did I get screwed?

I see the catalyst/honeycomb material which appears more like a metal baffle in the pipe, but is that the same as a catalytic converter? The seller assured me that the pipes do not have a catalytic converter. Did I get screwed?

Opps, sorry, didn't realize the first post (post #4) went through.

You don't have a converter in the head pipes...but you do in the mufflers. Bummer.

Looking into the pipes where the head pipes connect, the exhaust pipe stamped USA Catalyst has the gray honeycomb material, but the other pipe doesn't. What does that mean?

Thank you all for your info.
