2010 997.2 3.8 Turbo WC-GT exhaust muffler
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
Each system is hand built to order.



Manthey Racing Nürburgring 24 Hour Race Report
Congratulations to Manthey Racing and Porsche for an overall victory,
their fourth in succession!!
Stuttgart. Porsche
has won the Nürburgring 24 hour race for the fourth time in a row. Timo
Bernhard (Germany), Marc Lieb (Germany), Romain Dumas (France) and
Marcel Tiemann (Monaco) crossed the finish line in the 480 hp Porsche
911 GT3 RSR of the Manthey Racing team with a one lap advantage over
the second-placed Audi R8. The sister Manthey Porsche, the 445 hp 911
GT3 Cup S manned by Richard Lietz (Austria), Wolf Henzler (Germany),
Emmanuel Collard (France) and Dirk Werner (Germany), occupied third
position. Seven Porsche race cars finished in the top ten.
A
total of 235,000 spectators witnessed the fastest 24 hour race in
history on the Nürburgring. Clocking up 3,933 kilometres, the Manthey
Racing squad improved on its own distance record from 2006 by a further
101 kilometres. Timo Bernhard and Marcel Tiemann are the first pilots
to win the long distance classic four times in succession. All in all,
Tiemann has climbed to the top of the podium five times, making him the
most successful pilot of the 24 hour race.
Already in the early
stages, the race turned into a thriller. For almost one hour, Marc Lieb
followed in the slipstream of the pole-setting Ford GT driven by Dirk
Adorf. Only when the Ford spun after lapping a slower vehicle and fell
back, did Lieb get a free run. Until the early morning hours, the
winner of last year was entangled in a gripping duel with the fastest
of the Audis. As the regulations allow the more powerful R8 LMS a
20-litre larger fuel tank, the Audi could turn out one more lap per
tank. “To counteract this we had to take more risks and turn one
qualifying lap after the other to stay in the lead,” says Timo Bernhard
describing his most gruelling 24 hour race to date. “It was only when
the Audi experienced technical problems that we could take it a little
more carefully during the last hours,” added Marc Lieb. For Romain
Dumas the most decisive factor in the race was: “All of us were able to
maintain this unbelievable pace and not one of us made the slightest
error.” For Marcel Tiemann a dream came true: “We wrote motorsport
history today. To win this race four times in a row with this team and
now become the driver with the most victories here, that means a great
deal to me.”
For team boss Olaf Manthey, the fourth consecutive
win was the best: “I’m incredibly proud of my entire team and my
drivers. I couldn’t imagine a better line-up than Timo, Marc, Romain
and Marcel. But that said, Richard, Wolf, Emmanuel and Dirk also
delivered a super performance with our 911 GT3 Cup S. It’s just a shame
that changing the drive shaft cost us 24 minutes. Otherwise we could
have brought home a double win today.”
Another impressive
demonstration of the renowned reliability of the Porsche 911 was shown
by the squad under Uwe Alzen (Germany). Sharing driving duties with his
all German line up, Sascha Bert, Lance David Arnold and Christopher
Mies, they brought home fourth place with their 420 hp 911 GT3 Cup,
which is raced in 13 Porsche brand trophy series around the world.
Head
of Porsche Motorsport, Hartmut Kristen, was impressed with the
consistently good performance of the Porsche teams: “Our customers ran
three different current Porsche racing models at this race: the 911 GT3
RSR, the 911 GT3 Cup S and the 911 GT3 Cup. All three were equally fast
and reliable. There is hardly a more impressive way to show that the
Porsche 911 is still the best sports car in the world. Congratulations
to Manthey Racing and all the other Porsche teams who did a great job
in their respective classes. Despite the new tank regulations clearly
disadvantaging the Porsche teams, the Manthey squad could still bring
home their fourth straight win. Still, that shouldn’t conceal the fact
that the regulations should be corrected. The efficient vehicles should
not be the ones that spend the most time refuelling in the pits.”

Introducing the Manthey Cayman S M315 Project car!
As many of us feel, the Cayman S has lacked slightly in a few main areas which allows it to become a true 911 beater. Manthey Motors has taken the initiative to unlock the hidden power and allow the Flat Six, 3.4 liter engine to run free! While keeping the everyday drive ability in tact, Manthey Motors has fine tuned the engine managment program to interact seemlessly with their full exhaust system to re-locate the horsepower we all feel like the Cayman should have been delivered with.
On our particular test car, we have performed the following modifications:
- Manthey Headers
- Manthey Catalytic Converters
- Manthey Muffler with dual tips
- Manthey Re-Programmed ECU
- Sport Air Filter
- Manthey KW Coil-Over Suspension

GMG Racing - 997 WC - GT2

Global Motorsports Group (GMG) has now taken delivery of a 2008 997 GT2. We are proud to be one of the first tuners in the world to offer a tuned version of the fastest production 911 to date.
Named the GMG WC-GT2, with the “WC” standing for World Challenge, North America’s premier road racing series sanctioned by SCCA Pro Racing, this car will feature all the current GMG modifications developed on our Speed GT 997 Cup car, with all the latest Motorsports derived technology applied and refined for the street. The new 997 based GMG WC-GT2 will feature the latest Motorsport derived technology applied and refined for the street.
Suspension: GMG's WC suspension components include new GMG WC fully adjustable sway bars (front and rear), adjustable control arms for the rear, GMG's GT rear dog bone kit, toe steer kit, thrust arm bushings and bump steer kit to work with the new revised suspension geometry and ride height. Level 2 will include revised Moton Club Sport dampers specifically valved to GMG's spec's with custom wound Eibach ERS racing springs.
Exhaust: A completely new GMG WC-GT Sport exhaust system with 200 cell sport catalyst has been developed that not only improves the performance and sound of the exhaust system it also ads no additional weight. The exhaust is complimented by GMG’s WC-GT Sport exhaust manifolds that aid in turbo response and lower EGT's to improve the already impressive torque curve.
Software: We have GMG WC-GT specific file, which is tuned for the GMG WC power kit. A first for any software tuner, GIAC's latest on the fly switching capabilities will be available to the driver offering them the ability to select the following programs; stock, 91, 93 or race (100/104 octane-unleaded) while driving by simply touching a button on GIAC flash loader. Power increase will range from 70 bhp up to 120 bhp over stock depending on the power package configuration and octane of fuel available.
Aerodynamics: A new revised front splitter which produces more down force and a revised rear wing extension and an optional wicker to maximize rear down force while minimizing drag. All components are made of the highest quality carbon/ Kevlar composite material and are a direct replacement to the factory urethane units. Additionally, a carbon/Kevlar bonnet and wider front fenders to accommodate 10.5" wide front wheels will be available by mid July.
