Give your 2008-2009 Pontiac G8 GT 6.0L race-proven performance and a powerful deep muscle-car sound to match, with a PowerFlo Rear-Axle Back Exhaust System from SLP Performance Parts. This system will give your G8 GT a 7hp increase over stock. This exhaust kit includes a pair of our PowerFlo mufflers, which uses a straight-through design and fibre-wrapped perforated core to significantly outflow traditional chambered and turbo-type mufflers. Combined with our all new custom tailored G8 GT 304SS tip, you'll really feel, hear and best of all SEE the difference!
