Supersprint has a real performance exhaust available for the 2010 -> 2012 PORSCHE 997 GT2 RS 3.6L.

For some unknown reason, the stock exhaust is under-designed, putting a serious damper to the potential of the 620hp-rated engine.
It uses tiny headers (the very same stock/factory parts that had been developed for the regular 420hp 996 TT a decade earlier), a set of extremely restrictive, ceramic-substrate catalytics, and a very short-lived, crack -prone titanium muffler.
Ultimately, the std exhaust system can be considered an embarassment to this exclusive car, to say the least.
Ironically, only the R&L oval tail tips seem to be up to par.
The Supersprint tubular headers and exhaust is the perfect cure for all those issues, guaranteeing substantial Hp gains and better torque, a greatly reduced heat soak for a more consistent engine performance, a magnificent flat-6 sound, and an unsurpassed durability, at the same time.
