It's well known that one of the G8X's weaknesses is its lack of an aggressive exhaust note from the factory. You'd expect an attractive soundtrack from such a performance-oriented car but it's just not there. Fear no more for Dinan gives you their G8X valved axle-back exhaust so you can take full advantage of your vehicle's exhaust note whether you want a sporty aggressive sound or a refined subtle sound depending on the situation, all with the push of a button! Features: Maximum gains of +6 HP and +5 lb-ft of torque Enjoyably louder, sportier sound Drone abatement technologies used to reduce cabin resonance Four, diffuser filling, 4.5-inch (114mm) double-walled, polished stainless steel clamp-on tips with laser engraved Dinan logo Larger diameter piping for increased flow (76mm vs. 70mm) 6-pounds lighter than the stock axle back (Stock: 44-pounds vs. Dinan: 38-pounds) Stock exhaust valve actuators are reused, and the operation of the exhaust valve is unchanged so the exhaust tone can be adjusted via the M-drive settings Computer-controlled exhaust valves are retained and limit noise during low-speed driving and open fully during high-load conditions 100% 304 Stainless Steel construction Factory-like fitment with included mounting hardware
