  • Raven Muffler Plug

    Great Value

    Great Muffler moisture plug! My son runs an empire exhaust on his TRX450r and this plug fits great! Price is amazing.. I was able to buy a bunch for the price of some of the big name plugs.

  • Pro Circuit Platinum Pipe

    Pro Circuit Platinum Pipe

    IMO, this is the best pipe for my KTM 250SX. It has good bottom end, mid range and much better top end than an FMF pipe. I only ride moto with this bike and after having it on the bike I doubt I'll run any other pipe. Fit and finish is excellent. My only gripe is it *does not* come with the O-ring gaskets for the exhaust port.

  • KTM FMF Factory Fatty Pipe

    Adam in CO

    Best 300 pipe

    By far the best pipe for the ktm 300. Gives you more over rev vs stock and way smoother power vs pro circuit.

  • FMF Power Core 4 Hex S/A Silencer

    Avel in FL

    High quality product you can install yourself that'...

    Excellent silencer. It came with a spark arrestor that you can either leave off or install yourself. What I liked about FMF product is that they offered a spark arrestor option which had a longer tube which brought down the decibels so that I qualified for my harescrambler races. The fit and finish of the silencer is excellent. After owning it for a while now I feel that it added a little bottom to mid range to the bike. High quality product you can install yourself that's valued priced.
