The (991 GT3 & GT3RS) GMG WC Center Section is a direct bolt-on replacement of the factory center section. Handcrafted out of US-Made T304 Stainless Steel and meticulously TIG welded to aerospace specifications. A brushed finish is standard and a satin-black thermal ceramic coating is optional.
Weighing in at eight pounds, the GMG exhaust system is fifty 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 produces deep, aggressive, exhaust notes at lowers revs, and an exotic wail at higher revs.
Our WC Twin Tip Center Section is 100% emissions legal and will not void the factory warranty. The exhaust is a direct replacement to the factory exhaust, no modifications required. Installation is as easy as removing the factory center muffler, and replacing it with the GMG Racing WC Center Section Exhaust as it will bolt up to both the stock side mufflers while retaining the factory sport button’s function.
Installation is available for local Arizona clients.
