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.
The only thing that a
modified Raptor using this system will not
pass is 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.
For Raptor 700s with less drastic modifications such as:
Pro Flow Intake system.
Airbox cover removal.
Minor Head Porting.
DMC EFI.
Mild Cam. we recommend the DMC Raptor700 Twin system
25427-00.
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.
To enhance your quest for more performance, get
your paws on a DMC EFI Control Module. Our testing has proven this
combination of exhaust and an EFI Control Module to be a lethal combination
resulting in maximum output in horsepower and torque It's specifically
mapped to work in conjunction with your DMC Exhaust to deliver every ounce
of torque and horsepower in a smooth and responsive power curve. It's fully
adjustable with three simple buttons on the faceplate to adjust the fuel
curve richer or leaner in each area of the map. Advanced engineering
eliminates the need for complicated computer programs or interfaces.
Everything is controlled directly on the EFI Control Module.
