The GMG 996 Turbo exhaust is a race bred system that further increases overall performance, enhances sound, and reduces weight.

Handcrafted out of T304 Stainless steel and meticulously TIG welded to AWM aerospace specifications with great precision, the system is lighter than the factory. The system features high flow German made HJS HD 200 cell sport catalysts and a crossover x-pipe to increase power by balancing the exhaust gas pulse coming from the engine and adds to the signature sound that only the GMG WC system can offer.

The crossover x-pipe works by balancing the exhaust pulses from either side — or cylinder bank – of the engine. It allows the exhaust gases to flow down the path of least resistance while speeding up exhaust velocity. At lower revs, turbulence is formed as exhaust gases try to shuffle past a second column of gases coming from the other side. The X-Pipe merges the exhaust into two uniform streams, allowing a smooth flow from engine to exhaust exit.

Using the factory bracket location, the exhaust system is a direct bolt on replacement for the factory system. To ensure no CEL (Check Engine Light) and proper operation of the vehicle, the HJS HD catalytic converters are OBD2 compliant and the O2 sensor bungs are placed at their proper locations.
