Exactly. My buddy put some on his banshee when he installed his PC pipe kit, his shee runs sweet--the powerband comes on nice & smooth, no jerky, kick-your-ass powerband hit. With the wrong jetting though they may not work quite as well, I don't know if you have to rejet when you put them on or not. But they're pretty slick, good mod for the price I guess, I'm going to get some myself here pretty soon.
