In physics, a force is a pull or push that can cause an object with mass to accelerate. The DMC FORCE-4 Megaphone System produces maximum force (horsepower/torque) to accelerate your modified Raptor 700 harder than other any exhaust system on the market.
Like the 2-stroke pulse chamber, scavenging is maximized with the twin megaphones, delivering maximum engine efficiency. The reverse cone of a megaphone “times” the negative wave pulse reflection to correspond with the period of valve overlap. This low pressure helps to pull in a fresh intake charge while the intake valve is opening, This low pressure also helps to remove the remaining exhaust gases before the exhaust valve closes.
DMC Force 4 Exhaust will not pass a 96db sound test.
This is a true bolt on system and fits all Raptor 700 models with no cutting, bending or hacking involved. The DMC Force-4 is produced using 100% Stainless Steel headers and megaphone construction. Large diameter max-flow individual headers are easy to install and mount on each side of the Raptor, with the entire system tucking neatly inside the frame rails.
Extruded and hard-anodized twin aluminum mufflers sport stainless steel inlets and outlets and are easy to repack with high temp muffler-packing cartridges. Each system also includes black anodized alloy heat shields, precision laser cut Stainless Steel flanges, and USDA approved Spark arrestors. Custom megaphone tuning is easily accomplished using our optional rear cone inlets.
This system was created specifically for Raptors with some, if not all of the following modifications:
• Big Bore/Stroker up to 900cc+
• Race Ported head
• Oversize valves
• Race Cam
• Nitrous System
• Throttle Body modifications
