Drew Marine LLC is introducing the new Shotgun Exhaust
Flow Management System. With new J-2005 SAE test laws in effect in most
states, the need for even quieter exhaust silencers is more important than ever.
The new Shotgun EXFM is a three-part system: the Shotgun III, a Nascar silencer insert and an exhaust port. The
Shotgun recoil cylinder has a stiffer spring and used in conjunction with a
variable butterfly, the system adapts to changes in exhaust resistance and RPM,
which provides a quieter exhaust on large cubic inch, large cammed motors while
still allowing the development of maximum horsepower. The Shotgun also meets
several states' laws that require a full time silencer.
This new system
is made entirely in the USA with 100% 316 stainless
steel.
