No need for the spark arrestor?

The Stainless Steel Thrust Nozzle will give you better power than running without the stock end cap. Power gains as good as or better than some complete aftermarket systems! Louder and throatier sounding than the Thrust Chamber, but still more stealthy than aftermarket mufflers. Replaces the stock spark Arrestor unit.  Install with our Thrust Chamber for a more sano look.
