Unfortunately, FullSac doesn't make baffles for the Springer cans. I've used
smartpartz.com Hard Kore Quiet baffles on other mufflers, and they work well to quiet them down. Check their web site and select the V&H group, but if they don't show yours, they have a diagram where they show you how to measure your mufflers and baffles, and they can check that size against what they already make. That's what happened with mine; I have some Kuryakyn/Crusher Mavericks, which they don't carry, but the quiet baffle they have for the Hard Krome 2.5" was a perfect fit. Easy install and well made baffles that worked great. Oh, and Chris, who I spoke to several times there, is very helpful and knowledgeable. Once in a while I had trouble understanding his Australian accent, but a great guy.
BTW, I had tried a set of Big City Thunder QQ quiet baffles for a different muffler, but I had to get the baffle that fits in the header. Only removed about 10% of the sound, so wasn't nearly enough.
