Need help identifying an exhaust

[ElFuegoBlanco]

My RD400c came with these pipes. I'm hoping someone can help identify them. I don't want to go through the work of cleaning them up and painting them if they're trash. I'm not looking for anything high performance. Just reliability, really.
I know a few pictures isn't much to go on, but I figured I'd throw it out there anyway.

i think those are coffmans.

Thanks. I'll go ahead and try cleaning them up. I have some high temp paint I can use.

I considered just wrapping them to make my life easier, but might as well just paint them. It'll be at least a few more weeks before I'm ready to mount them anyway
