The Competition Series was designed and tested for Sport ATVs and Dirtbikes. The Trimax Core features 3 levels of power and sound. Included with every exhaust are 3 inserts that effect the sound and power differently, giving you complete control and allowing you to dictate the type of power and sound you need, when you need it.
Backed by the ATV legend Mike Penland, the Penland Pro Series was developed for serious off road racers and trail riders striving to achieve more low end torque. The removable Torque Range Modifer adds a low-to-mid range punch, allowing quads to hook-up better in rough conditions.
The Performance Series has a specially designed, unrestricted core allowing the system to increase power evenly throughout the RPM range. It features the deep HMF tone with industry-leading end cap and color options, giving you a completely custom look and sound.
The original quiet race exhaust, the Quiet Race Series features an internal mechanical core that controls sound pulses and manages them to a minimum. The Quiet Race Series?s core will help you meet sound regulations in most restricted riding areas.
The Swamp Series is so unique because of it's 5-inch diameter shell. It gives the exhaust more internal volume which, in turn, produces larger horse power gains. The large mechanical core directs and controls sound pulses to keep sound levels approximately 1-2 dB over stock. It?s shell is made of 304 stainless steel and the inlet is TIG-welded shut for a water tight seal.
The younger brother of the Swamp Series, the Swamp XL (extra loud) offers slightly more horse power than the standard Swamp Series. What makes this exhaust different is the non-restrictive core. Since there is nothing inside the core controlling sound pulses, the exhaust is louder than ever. Strap this to your machine and we guarantee you will be heard by everyone.
