It retains the factory computer-controlled exhaust valves, so closed valves route gas through the Dinan muffler and out the inner tips for subdued low-speed cruising, while open valves bypass the muffler under load for a near straight-pipe roar. Drone abatement technologies inside the muffler keep cabin resonance in check, and the complete system runs 6 pounds lighter than stock. Peak gains reach +6 HP and +5 lb-ft, finished with four double-walled 4.5-inch clamp-on tips laser engraved with the Dinan logo.\u003c\/p\u003e\u003ch2 style=\"margin:16px 0 4px
