Bill, just some thoughts, if the mufflers are flat black, I would tend to keep the system uniform and go all black or all white. I've had my system white for eight years now and it is tough to keep them clean. You can respray periodically in place but you have to mask the engine bay, which is again tough. I used VHT paint the last respray and like it so far. For what it's worth, you might just go black and save some trouble down the road. If you're still doing the gulf theme, they were black as you know. On my friend's Daytona coupe replica, they ceramic coated in white, which failed, recoated in silver, and then painted them white.
