The GMG Porsche 991 GT3 Center Section is a direct bolt on replacement exhaust system. Handcrafted out of US Made T304 Stainless steel and meticulously TIG welded to aerospace specifications with greater precision, the system is lighter than the factory system and surpasses the factory piece in terms of quality and performance. Weighing in at 7 pounds, the GMG exhaust system is 30 percent lighter than the factory system and features a proprietary megaphone design to improve sound and performance throughout the entire rev range. The GMG center section increases approximately 3-5 hp on average and produces deep aggressive exhaust notes at lowers revs & exotic high pitched exhaust notes at higher revs. The WC-GT Twin Tip or Single Tip Center Section is 100% emissions legal and will not void the factory warranty.
