I received a set of used Cyclone Headers for free and I was wondering if anyone ever heard of these. I have not, and I would like to know if they are good or junk?

They are for a 340. The photo is one I found on Ebay.

I am not rich...but I get off my ass everyday to make sure I am not broke!

Can we get the Mexican cartels to help us with our supply chain issues? They don't seem to have any trouble getting stuff from one place to another.
