The new era of exhaust systems begins right now. In a completely revolutionary design, the DMC Alien incorporates a completely new exhuast technology adopted from hydrodynamic flow theories. DMC Aliens use separate header pipes for each port to supply maximum scavanging,
creating a superior combustion chamber "fill" and flow. The tapered Alien Muffler combined with mathematically precisioned core position and sizing is the key to performance. The exclusive and re-designed dual pulse chamber system actually operates like a "variable" tuning device at different RPM's to deliver maximum torque and horsepower at virtually every engine speed.

K&N Replacement Air Filters are ideal for extended use in dirty and dusty off-road riding and provide clean carburetion even at high altitude. As a rule, no jet changes are required with just a K&N filter element, however the spark plug condition should be checked for proper mixture after the first few miles of riding. If the airbox has been modified for increased air flow, the main jet size will need to be increased to provide the proper fuel mixture.

SERVICE HINT: Do not clean the K&N air filter too often. When a drop in performance is noticed, or the machine becomes hard to start, it is time to service the filter element. The dirt build-up actually helps stop more dirt and does not hinder the airflow.

Available for: 250R, 400EX, Banshee, Raptor
