Part No. 06-233.FMF.PBS Yamaha WRF450 YFZ450 2004 - 2010 & 2012 - 2015,,, 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. 2005 Yamaha WR450F 2004 Yamaha WR450F 2003 Yamaha WR450F 2013 Yamaha YFZ450 2012 Yamaha YFZ450 2009 Yamaha YFZ450 2008 Yamaha YFZ450 2007 Yamaha YFZ450 2006 Yamaha YFZ450 2005 Yamaha YFZ450 2004 Yamaha YFZ450 2007 Yamaha YFZ450BB Bill Ballance Edition 2006 Yamaha YFZ450BB Bill Ballance Edition 2004 Yamaha YFZ450LE Limited Edition 2007 Yamaha YFZ450SE Special Edition 2005 Yamaha YFZ450SE Special Edition 2007 Yamaha YFZ450SE2 Special Edition 2 2006 Yamaha YFZ450SP 50th Anniversary Edition 2008 Yamaha YFZ450SP Special Edition 2008 Yamaha YFZ450SP2 Special Edition 2 2006 Yamaha YZ450F 2005 Yamaha YZ450F 2004 Yamaha YZ450F 2003 Yamaha YZ450F
