(Tango1300 @ Jun. 22 2007,15:05) I had this same question last year... Charles at Street N Track sent me the TiForce Sumo and I weighed it at 9.26 pounds WITH the billet bracket! I thought the box was empty when it arrived!
The install was flawless and I did it in my Hotel packing lot with the tool kit the bit came with! The sound is awesome and I would never suggest another exhaust system for the Busa.
