My Softail has V&H Big Shot exhaust, and they're loud. I was hoping to quiet them down a bit with some Big City Thunder Quiet Baffles. But they're not much quieter than the stock V&H baffles. I did have the bike tuned and it does run a lot better, did gain some low end back with the BCT baffles. But it's still loud. If you're thinking of buying the BCT baffles to quiet down your exhaust, don't.
