PRO MOTO BILLET / FASTWAY SPARK ARRESTOR END CAP

The best power gain for the least money in moto is right here with the PMB End Cap. Fastway by Pro Moto Billet’s Spark Arrestor is a fully billet CNC machined 6061 billet aluminum end cap with a U.S.F.S. spark arrestor..  Installation is super straight forward and simple, you'll need just regular shop tools and a drill.  The stock muffler outlet port on a KTM EXC is 28mm! Sit with that for a second. A 500cc bike with a 28mm outlet port?! But the inter muffler pass through pipe is 42.5mm.  So if you want an end cap that's also got a 42.5mm outlet port then the PMB cap is here to save the day. We see a 4-9% power boost with these installed - of course with fueling sorted out, and we highly recommend the Dobeck EJK which we also offer and support.  Also offered separately is a silencer insert witch scrubs the bark by up to 8db's over the unmuffled unit. *May require fuel tuning on certain bikes. Call us if you have any questions.
