  • Polisport Armadillo 2-Stroke Pipe Guard

    Dalton in WA

    Looks good. Doesn’t protect

    Looks good. In terms of actual protection for your pipe you’d be better off using the cardboard box it comes in. I’ve had the plain metal ones in the past and have been happy with the protection to cost ratio. This offers no protection at all, but it does look good.

  • Raven Exhaust O-ring & Spring Kit

    Good but came with only one spring

    I assume it's supposed to come with two springs but only came with one!

  • FMF Power Core IV Modular Quiet Core Insert

    Greg in OK

    What a difference!

    Installed in 5 minutes. Makes the powercore 4 less obnoxious. I felt like I was annoying other riders. I was about to put the stock muffler on until I ran across this insert. Makes a huge difference at idle and low rpm. It takes a lot of the bark out of the sound. Without the insert, my decibel app on my phone was pegged at 90db. Once installed, the app was showing an average of 79db at idle. Whether those db readings are true, who knows. But the difference in levels is remarkable. The pipe is still loud at high rpm, but does seem just a bit quieter. It also crackles a bit when I give her the beans...still, I love this insert and will never ride without it.

  • FMF Q4 S/A Silencer

    Bradley in VA

    Great boost in performance

    This silencer coupled with the Power Bomb header really improved the power throughout the entire RPM range for my recently restored 440EX. I also like how the quad is not stupid loud. Great setup.
