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.
