I used the search and I didnt come up w/ ne thing. I just purchased the QFLOW and installed it. Sounds great and I can feel a little top end pull and it deff. revs smoother. The only questing that I have is...The tube coming from underneath the engine cover going to the bottom of the airbox is exposed now. I believe its a breather hose but Im not sure. Does ne1 know if it is and if it is do I just go buy a little breather filter to close it up.
