A very good client of ours recently delivered his already potent Porsche 997.2 Turbo S to us for both the GMG exhaust, intercooler, and GIAC software upgrades. Together, these upgrades netted an increase of almost 89 horsepower and 98 foot pounds of torque, approximately a 23% increase over stock.






























GMG Porsche 997 Turbo S Exhaust System

Constructed out of T304 Stainless steel and meticulously TIG welded to AWM aerospace specifications with great precision, the GMG Porsche 997 Turbo exhaust system is 30 Pounds lighter than the factory system. The system features OBD2 compliant German made 200 cell sport catalysts to ensure no CEL (Check Engine Light) and a proprietary crossover x-pipe to increase power by balancing exhaust gas pulse coming from the engine and adds to the signature sound that only the GMG WC system can offer.

Our proprietary crossover x-pipe works by balancing the exhaust pulses from either side—or cylinder bank of a V-style engine. It allows the exhaust to flow down the path of least resistance. At lower revs, turbulence is formed as exhaust gases try to shuffle past a second column of gases coming from the other side. While always producing more power than the restrictive factory system, the potential gains are not seen until higher rpms are reached. This is where an X-Pipe stands apart from the rest. Exhaust gas is pushed out harder as the engine spins faster. The X-Pipe merges this chaos into two uniform streams, allowing a smooth flow from engine to tailpipe. Both streams keep each other up to speed, which draws even more spent exhaust out the cylinders.

The exhaust system is a direct bolt on replacement for the factory system.
