STG Titanium Exhaust Manifold Stud Kit
Porsche 911 997 Turbo / GT3 / GT2 (Gen.1)
Upgrade one of the most failure-prone fasteners on the Mezger engine with a motorsport-grade solution engineered for extreme heat, pressure, and longevity.
The STG Titanium Exhaust Manifold Stud Kit is designed specifically for 997.1 Turbo, GT3 and GT2 models, replacing the factory steel studs that are notorious for corrosion, seizure, and snapping during exhaust or turbocharger work.
Manufactured from aerospace-grade titanium, this kit delivers exceptional heat resistance, strength, and corrosion immunity — making it the definitive choice for both road and track-driven cars.
Why Upgrade to STG Titanium?
Exhaust manifold studs on Mezger engines live in one of the harshest environments on the car. Heat cycles, moisture, and road salt quickly degrade OEM hardware, often turning routine exhaust jobs into costly engine-out nightmares.
STG’s titanium solution eliminates these issues:
-
No corrosion
-
No seized threads
-
No snapped studs
-
No compromises
Once installed, these studs are designed to stay serviceable for the life of the engine.
