What are TC/Supertrapp silencers made of?

I'm wondering what kind of metal the black part of TC silencers is. Does anyone know? Thanks.

its part of the 350x supertrapp system. It looks like he buys the mid pipe and silencer for a 350x system and cuts and rebends the exhuast to work.

here it is installed on my 86 200x. he cuts and welds a new section on where the cone section ends.

I was going to have to add a few inches to the end of the silencer in order to meet the headpipe on my hybrid. I didn't know if I should use regular exhaust tubing, or what. Any ideas?
