Audi R8 V10: GMG Racing WC-GT Exhaust System

Audi R8 V10

Redline Speed Worx (RSW) is Proud to present the GMG Racing World Challenge Exhaust system for the Audi R8 V10! The GMG Audi R8 exhaust is handcrafted in the USA out of T304 stainless steel and is meticulously TIG welded to AWM aerospace specifications with great precision.

The system features 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-GT system can offer.  Our proprietary 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.

At lower revs, turbulence is formed as exhaust gases try to shuffle past a second column of gases coming from the other side. This is where an X-Pipe stands apart from the rest. 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.

Using stainless steel packing material in the mufflers, the GMG exhaust is designed to withstand extreme exhaust temperatures and high intensity acoustic pressures. This is one of the key advantages of the GMG exhaust system since many competitor exhaust systems use fiberglass packing instead to lower costs, and they are prone to rapid deterioration.  The exhaust system is a complete drop-in upgrade using existing factory hangers and is 50 states emissions legal.

The 2014 V10 Audi R8 Spyder is in the shop for it's GMG Racing WC-GT Exhaust System Installation appointment!

Audi R8 Performance Exhaust Install

This V10 is shedding pounds quickly!  On the V10 Spyder as well as the V8 R8's, extensive panel removal is required in order to get the factory system off the vehicle. Our skilled Service Team makes quick & efficient work of the Audi's tear down to ensure a seamless installation.

The R8's platform provides the owner with ample space in the engine bay if one were to decided to twin turbocharge the V10, just an FYI ;)

R8's need turbochargers

The precise fabrication by GMG Racing on the V10's upgraded exhaust system is demonstrated at the point of installation. Not only does the complete system fit the factory heat-sheild perfectly, it greatly reduces the overall system weight when compared to the OEM Factory (Restricted) exhaust.

With the system now fully installed, and unfortunately almost a 100% concealed, all that remains are the dual single round exhaust "exits" that mate perfectly to the updated 2014 model year R8 V10 rear bumper assembly.  It's time to take this bad V10 out for a test ride! Video coming soon!
