2015 rgs with stage IV kit, v&h header pipes with cfr mufflers.I'm reading that the cfr's are not the best mufflers. Looking for info on what are the best??Thanks.

I know from experience there are difficult to tune, they lacked real backpressure for proper scavenging, im not sure but I think they did change the internals on the new ones, a lot of members seem to like em, I personally think there a tad bit loud for me, and on long trips droning is common, I just purchased MGS slip ons and am very happy with them, price was right on point as well, Good luck with whatever you choose.
