These Hard Enduro edition mufflers are about 3" longer than "stock". This provides more backpressure to the engine enhancing low end torque and smoothing out the top end. Graham, alfredo, etc. all run these longer mufflers on their race bikes for that extra edge! Together with the expansion chamber that broadens the power range these mufflers make for the full package!
These mufflers are NOT spark arrestors. This is close to the stock length, and runs great!
