michael a:If you're just going to install the slip on with a stock air cleaner, you should be fine... Just keep in mind that your bike is tuned on the lean side from the factory...FYI the catalytic converter is in your head pipe... So you will gain some sound but, not as much with a different head pipe as say an off road or cat-less head pipe.. Wink winkJan 19, 2015
Sandeep M:I agree with michaels answer above, but i will add that I found retuning my bike with a fuelpak FP3 made a big difference. Eliminated almost all the decelration popping and the overall get up and go improved very noticeably.Apr 15, 2015
