I already have a K&N air filter. I'm buying a Yoshi RS-3 bolt-on. Which kit should I get...the #1.0 Supersport kit or the #1.1 Ti Prokit. I'm leaning towards the Prokit, it's only $20 more. And if after a while, I decide to get a full exhaust, will I need to get a new jet kit? or can I use the same kit?
