Recently, I've had my pipes save me from some potentially very nasty situations. One situation in particular was in congested traffic and a distracted woman, talking on a cell phone when she decided to take my spot WITHOUT looking, and I know she didn't look 'cause I was watching her. I very quickly pulled in the clutch and blipped the throttle and she darted back. Problem avoided. I ride very defensively, as if ppl are trying to kill me. Cell phones should be banned completely while driving, they are a huge problem... loud pipes may be a temporary nuisance but distracted driving costs lives. I knew a local couple were killed by a cell phone distracted 21 y.o. female 18 months ago.... They left 3 kids behind. And I also know there are idiots that abuse the pipes by blipping the throttle incessantly or blasting where they shouldn't but honestly, that is the least of our problems in the bg sweep of things.
So, emphatically YES!! they work. No BS, no nonsense... get over it.
