Exhaust baffle recommendations
I'll be brief!
V-star 650 with stock air, stock carbs and unbaffled Cobra Drag Pipes (as I bought it): exhaust noise and timbre "within the realm of reason". I could conduct a conversation in my garage without shouting, for example.
After a GAK kit and carb mods (shimmed needles, 91->127.5 main jets): so staggeringly loud that it's impossible to speak inside the garage without shouting. The timbre is unpleasant, best described as "high, percussive and metallic", like a giant set of trip hammers beating on a hollow aluminum cylinder over and over.
But the idle doesn't really bother me so much since I don't idle my bike to impress people; the real issue is that once you get past around 1/2 throttle, the thing really gets going and sounds like a nitromethane funny car, just one long ripping explosion that can be heard all the way on the other side of town if I'm not careful. My buddy's opinion: "As loud as a Harley with straights, but more ripping instead of rumbling." If there's police and pedestrians about, I have no choice but to lug the thing in 5th gear as quickly as possible right out of my driveway until I get out of town and can safely open her up.
In short: I'm looking for some kind of a screw-in removable solution in place of the lollipops that I can use when I'm just puttering around town. If it'll require rejetting, that's obviously a no-go. I already tried lollipops made from thumbscrews, which help a lot with low-end torque but virtually zero with noise.
