Comprising of aerospace grade T304 stainless down pipes with high-flow catalytic converters and mid-section resonator delete, the GMG Porsche Panamera exhaust package increases performance and helps produce a more aggressive sound.
The GMG exhaust package allows for a quicker turbo spool while increasing horsepower and torque throughout the power band. On a stock Porsche Panamera Turbo, the exhaust system is very restrictive by design; using (4) catalytic converters total, there are (2) per exhaust bank. On each exhaust bank, there is a primary and a secondary catalytic converter. To increase power and flow, the GMG design eliminates the secondary cats entirely - using only (2) primary German made high flow 200 cell catalytic converters - and replaces the factory resonator with an crossover x-pipe to balance the exhaust gas pulse.
The crossover x-pipe increases power by balancing exhaust gas pulse coming from the engine and adds to the signature sound that only the GMG WC-GT system can offer. By balancing the exhaust pulses from either side — or cylinder bank - of the engine, the crossover x-pipe 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. The 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 the engine to the tailpipe. Both streams keep each other up to speed, which draws even more spent exhaust gases out of the cylinders.
The high-flow catalytic converter/downpipe is a complete drop-in upgrade. Using CNC machined flanges to prevent warping and expansion, and factory exhaust hanger locations, the system will bolt up to factory turbo and mufflers. To ensure proper functioning and no CEL, 2 oxygen sensor bungs are placed at the proper locations.
