We are proud to be one of the first tuners in the world to offer a Sport Muffler solution for the 2010 997.2 Turbo. Porsche has redesigned the exhaust system on the new turbo and has made the system modular which allows for replacement of the muffler section without replacing the catalyst, a feature that was not available for the 997.1 Turbo.

Our new World Challenge Sport center section utilizes our race proven cross over center section with proprietary dual core mufflers and a megaphone design which improves the sound and speeds up the exhaust velocity as the exhaust exits the catalyst. (patent pending design) Made entirely of T304 stainless steel that is handcrafted at our facility. The entire system utilizes mandrel bent tubing, in addition the mufflers are hand built and utilize stainless steel packing throughout. The system is purge Tig welded by hand and all welds are normalized to prevent cracking. Each system features a GMG exclusive brushed finish. (A mirror polish as well as ceramic thermal coating is available as an option).

As with our World Challenge GT system for the 997.1 Turbo the WC-GT 997.2 Turbo system produces a refined sound reminiscent of the Carrera GT and without drone.

• The muffler is 50 State Emissions legal and will pass smog
• Weight 15 lbs
• Bolt to factory catalyst and tips
• *Optional Sport catalyst and GMG WC- GT quad tip available at additional cost
