Just happened to check HMF's website and they have the 2013 muffler on the website finally for the RS model. No video to hear what the pipe sounds like so anyone want to be the test mule? From the earlier model pipe I like the HMF sound and what's not to like about the HMF price...lol.. I figure this pipe will not be as loud as earlier pipes on the RS since we will still have the cat in place. And for the same reason I figure there will be no need for a tuner on the 2013 when adding the muffler only.
