THE OLD MODEL TM TORQUE HAMMER EXHAUST FOR BUELL XB MODELS from 2003-2007. Because we developed a new model look here: it is now special priced, gone is gone.
They are made from RVS (stainless steel) and polished, with mounting brackets. IT WILL HAVE THE MOST HP and TORQUE (WITH A GOOD TUNED ECM), COMPARED TO OTHER EXHAUST PRODUCTS FOR YOUR BUELL.
Here is the article of the Torque Hammer tuning:
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.
