The (991 GT3 & GT3RS) GMG Center Bypass 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 in Southern California. A brushed Stainless steel finish is standard and ceramic coating is optional.
Weighing in at only 7lbs, the GMG exhaust system is 30% 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.
The Center Section (Center bypass) is 100% emissions legal and will not void the factory warranty. It's a complete bolt-on upgrade, utilizing factory exhaust bracket locations, which will bolt up to both the stock primary mufflers while retaining the factory sport exhaust option. Hit the Sport button and listen to the beautiful exhaust note.
Twin 4" tips that fill the bumper perfectly.
