STG Titanium Exhaust Manifold Stud Kit
Porsche 911 (991) GT3
Engineered for extreme heat, relentless track use, and uncompromising performance, the STG Titanium Exhaust Manifold Stud Kit is the definitive upgrade for the Porsche 911 (991) GT3. Designed to replace the factory steel hardware, this kit delivers superior strength, reduced weight, and long-term reliability in one of the harshest environments on the car.
Manufactured from aerospace-grade titanium, each stud offers exceptional resistance to heat cycling, corrosion, and galling—common failure points of OEM fasteners under repeated high-RPM and motorsport conditions. The result is consistent clamping force, improved exhaust sealing, and hardware that remains serviceable even after prolonged track abuse.
Precision-machined for exact OEM fitment, this kit installs seamlessly with factory or aftermarket exhaust manifolds, making it ideal for track-focused builds, high-performance road cars, and full motorsport applications.
