Does Anyone have some good shape dual cat exhaust laying around?

Looking for the factory setup, mine was junk when I took it off.

Thanks!

Someone spent many hours detailing the undercarriage & it looks great!! Believe me I know. Been there done that on my '72 Buick GS. Great job.

Thanks and yes, I spent many hours. I restored every nut and bolt on the car. I stripped it down to the body, subframe and wire harness. Every other piece was removed, polished, painted or replaced.
