GMG introduces the RSR oval center section for the Porsche 997 GT3 and 997 GT3 RS models. Designed and tested on GMG's 997 GT3, this system is a direct bolt on replacement center section which reduces weight, improves sound and offers a mild increase in performance.
Our RSR Oval Center Section is 100% emissions legal, will not void factory warranty and is a direct bolt on replacement center section with dual 3.5 stainless tips (factory offers dual 3"). The system is made of Type 304 stainless steel and features a proprietary megaphone design to improve sound in the upper RPM range. The GMG center section system saves over 14 lbs. of weight and increases approximately 3-5 hp on average. GMG was the first company to pioneer this design.
Also available as a power kit is the GIAC custom tuned software for an increase of up to (real world) 15hp and 20lb ft. of torque (fuel dependent). Please inquire for special power kit pricing. The ECU must be sent into GMG for flashing and will be sent back same day via FedEx minimizing down time.
