PART NUMBER 06-240.FMF.PB (OFF ROAD ONLY) WILL FIT THE FOLLOWING MODEL/S YAMAHA ATV SPORT YFM660 RAPTOR 01-05 POWERBOMB STAINLESS STEEL FOR CLOSED COURSE COMPETITION USE ONLY. NOT INTENDED FOR STREET USE. The redesigned Powerbomb is a four-stroke header that incorporates FMF's patented Powerbomb module at a precise location in the initial stage of the header. By positioning this "Bomb" at a key point in the system, increased performance and flow is achieved through the expansion and contraction of exhaust Sonics through the system. Result is a flow increase of nearly 10%! The outer chamber in the Powerbomb allows the air to expand, cool and ramp back up at a higher velocity. Additionally, the Powerbomb is a "pre-muffler" of sorts which helps to lower the bikes sound output by providing more sound absorbing surface area for the sound medium (exhaust gases). On some models, you can choose between a moto or super cross version. The super cross version is designed for more low to mid-range power where the moto version is focused in the mid to upper RPM range.
