I put a black version on my V7C when he first started offering them. It has held up well, sounds great. It is a lot lighter weight than the stock exhaust as well. The black coating is very durable too. I scratched it when I was installing the exhaust, putting safety wire on the exhaust flange nuts. That was two years ago. Those are still the only scratches on it.
I just ordered another set for my V7 Racer, in stainless this time.
