Hi, I’m doing some research on exhausts for my 25 ST. Ideally I’d want one that’s adjustable like can be quiet when I want and louder at other times. I’ve been looking at the valvetronic exhaust but I have heard both good and bad. Ideally I’d wanna keep as much of the original exhaust as possible. I guess people are saying it’s too raspy but that can be fixed with an X pipe being installed. Anyone have any better insight or other recommendations that would be nice.
