Yes, it sure does! I never thought the exhaust had that kind of potential, lol. I believe it also disconnects that one valve which you play with during the "golf tee mod." Before this, my right-side exhuast tip would always be more dirty than the other (valve working), but now they're both equal. This, I'm sure, is also one of the reasons it gets louder. They basically give you the same result of a golf tee, along with whatever else they change that makes it sound so much nicer.
