Ive got t-force titanium on both the 07-08 single on the 07 dual on the08 ,must admit they sound awsome but the titanium is very light an prone to dents,you know it stinks when you put your trust an money into a company to do work on your ride and it comes back to you with that beautiful ti-force with its insides all dented ,their responce ,we did not do that,even though that job required the removal of the exhaust, nobody knows their bike like the owner.You know ide like too give their name but just incase i have to go back,got a lotta money invested,dont want any sabotage,you know how some people are espeicially when they wont even admit to making a mistake.Buy the way that was not all the service they gave me theres a lttle list,some people.
