I've ridden for hours at a time and was able to grab (with my entire hand) the CF part of the pipe without incident. It'll get warm, but CF usually never gets above 'warm' (from my experience). I'm positive that these'll work with your soft luggage.
these pipes sound MEAN and GROWLY AS F*CK.
people say they're on the loud side, but I don't get any complaints from people riding with me, my neighbours, or my girlfriend (who sits right above them).
And personally, I love the way they sound and look.
