Designed and tested on GMG's 997GT3 this system is a direct bolt on replacement center section which reduces weight, improves sound and offers a mild increase in performance. Porsche has done a wonderful job with the design and manufacture of the factory system with virtually no improvement to be made by installing a complete (mufflers, headers and cats) aftermarket system. GMG's WC Sport 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 mandrel bent T304 stainless tubing which is TIG welded and features a proprietary megaphone design to improve sound in the upper RPM range. The GMG WC system saves over 14 lbs of weight over the stock ( stock gt3) and (5 lbs over GT3RS with Ti muffler), power is up 3-5 hp on average and now the sound is finally worthy of this magnificent engine. GMG was the first company to pioneer this sport center section design. Also available as a power kit with GIAC custom tuned software for an increase of up to (real world) 15hp and 20lb ft of torque. (fuel dependant) Inquire for special Power Kit pricing. ECU must be sent into GMG for flashing,. ECU's will be sent back same day via Fed Ex minimizing down time.
