NOZZLES AND OTHER GOODIES
THRUST NOZZLE - Not Spark Arrested
No need for the spark
arrestor?
The 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. Can be
installed with our Thrust
Chamber for a more sano look.
