I was motivated mostly by weight savings for my '22 Speedmaster, a bit more growl, and to maybe get a bit more lean angle due to the more compact profile.
The sound is fantastic, louder but not obnoxious. At idle / low RPM it's still pretty quiet, which I appreciate - I don't want to be be a nuisance. More bass - deepness - growl to it, though. Twist the throttle, though and the sound comes ALIVE - raw, beastly, and dare I say aggressive.
I'm glad these are made in the USA as I like to support democratically run countries with my wallet. I will say the price is a bit steep given just how simple these pipes are - just one 90 degree bend - but in the end I'm glad I got them. Thanks BC!
