I don't know about durable, since I've only had the Bullets in the '57 since late summer. Buddy who's had 4" versions on his 10-sec MC for 3 years said something recently about believing they're pretty much blown out now.
At idle, it is a little loud. Under power, they crackle something fierce. Full throttle, quieter than open exhaust, at least. But, they didn't cost me any performance vs. open.
Shall we say "nervous" is a good description of my mental state when I'm driving home from the track after midnight.
