TM XB 9/12 Torque Hammer 2002-2007
We developed our exhaust on our dyno and achieved 110 NM of Torque, SAE CORRECTED on the rear wheel. We recommend for the 2008 and 2009 XB models to change the header to a 2007 model year(they are much bigger in size) and use our exhaust. It gives peak torque at 3000 PM.
