need a slip on for better sound without having to rejet and stuff. any thoughts?
No matter what you put on you will have to rejet.
I installed a white bros. e-series & did not have to rejet at all. If you install a complete pipe you will & if you replace the stock a/f with a k&n you will. Definite noticeable pickup in bottom & mid range plus a great sound. Oh yeah, I own a KFX400.
thanks
