K8 and Thirsty,
These are Rare NOS 4 into 2 pipes that I scored on sleaze bay and immediately had coated buy a local mom and pop auto shop that does ceramic on the side. He vibratory polished a set of sohc engine covers that turned out perfect, then somehow screwed up a set of gs1100 covers. So as a return favor he did these pipes for $100. I would recommend him for someone that is local, so if they have an issue they can go to him in person.
I have considered getting sets of covers polished then selling them.
