Exec muffler cover, Options?

Is their a way to get or make a stainless exhaust shield? Is the exec cover our only shinning option? I would like stainless to match my end wieghts. My other choice is to purchase a Yoshimura r-77 full exhaust ( carbon fiber) for an even better look with a power comander. If im going to spend rhat kind of money might as well squeeze sone extra speed out. Oh, can't forget the bmg air filter. If I go this route will this setup be detrimental to the operation of the bike?
