D&D Triumph America Speedmaster EFI Boss Slip Ons
The 2009-2014 Triumph America / Speedmaster now gets a kick in the pipes with D&D's Boss Slip-ons. They sport a large diameter muffler, which increases torque and horsepower. Each exhaust kit comes with a K&N High Flow filter from our friends at D&D Performance. Be heard and be happy with a sweet set of D&D's.
