Dinan's Free Flow axle-back replaces the factory rear silencer section with 100% 16-gauge 304 stainless steel, cutting back pressure to free up 4 HP and 3 lb-ft at 6600 RPM. Four laser engraved 70mm (2.75 in.) T304 stainless tips finish the system in a black ceramic coating. Drone abatement is engineered into the muffler so the cabin stays civilized at cruise while the tone sharpens under hard acceleration. The system hangs from the factory brackets and hangers, so installation is bolt-on with no cutting or welding.
