Larger diameter braided line...

I've been looking for some coaxial cable (cord? wire?) about 1/8 inch diameter or so to make flex joints for aftermarket exhuast systems. But, ummm.. no luck. I know nothing about electrical wiring sizes and such, does anyone else know where I could find this or something similar? Thanks!

Did you look at round elastic like you get in craft and sewing stores?
Just paint it black or silver, or use a black marker, the braided coating on the elastic will look like braided hose.

Hmmm... yeah, that would work, I guess. I'll have to look for some next time I'm out of town... Thanks!
