I have them on my14 Street Glide & I love them.. Look great & the sound is very unique..I am about to put a tuner & true dual headers.. When I called CFR I spoke to Carey, great dude & gave me the time I needed on the phone.. Highly recommend them!
Just to update an old thread. I put the CFR's that were on my 98 roadking on my new 17 freewheeler with the new M8 (fit fine) and love them even more. I've got the wood 22X cam, Arlen Nes heavy breather and power vision tuner. The deep sound is like none other but is not overwhelming. Just a great deep sound that doesn't interfere with listening to my iphone music with deep canal ear plugs. From what I've read I may be loosing a bit of low end torque but I'm almost always above 2500rpm and I can easily raise my front tire off the ground in first and chirp the tires in second gear. 30k miles and still look and sound great... haven't had it dyno'd yet, just a new map from fuel moto and my own auto tunes.
