Time to ask the question now that the warranty period has expired.  I want to add sound and grunt to the 2019 CVO Streetglide.  The 117 is stock at the moment, I am thinking of Bassani headers, S&S 4inch mufflers, a tuner to sort this out and a change to the Screaming Eagle torque camshaft.  What do I want to achieve?  More torque, not worried so much about power gains, not too much noise, but, would love a potato potato loopy idle.  Sorta like my old Evo, which was gutless but sounded horn.  Any recommendations?

Skip the SE torque cam and get something decent. Cycle Rama 480 from APE?

Like John said, 480 or one of the newer ones, M8's love a cam with a good tune.

yeah get a aftermarket cam like the Cr480 as the SE cam's are pretty tame really and are really for them who want to keep their factory warranty, I've been looking into cam's for my FXLRS 117 which is due to arrive in a couple off months (finger's crossed) and my biggest dilemma is what else I should replace? ie along with cam, adjustable push-rods, inner bearing and tune should I replace lifters (as i've heard they aren't that flash stock) lifter block guides and maybe oil pump & cam plate

The 117 has less compression, so be careful which cam you use. I just replaced lifters with hardening coming off the rollers at 7900kms..... 

OK, and thanks to others for the CR 480 suggestion.
