  1. Exhaust HELP!

    Engine/EFI/Drivetrain
    I am riding a 2008 kfx450r that I purchased a while back. Just recently my slip-on cracked and it's totally falling apart. I believe it is a Two Brothers M7 full system. I'm having troubles finding somewhere to buy just the slip-on. Does anyone know where I might be able to get one??

  8. Big 3 Comparison

    General Discussion
    I bought my 2008 KFX450 in excellent condition, low miles, and bone stock. I added an HMF slip on pipe, K&N intake, and an HMF optimzer. It sounds pretty good and in my opinion runs pretty good. I am pretty new to the sport and don't have much to compare it to. Apples to oranges, but I get...
