STG Titanium Exhaust Manifold Stud Kit - 911 997 Turbo GT3 GT2 (gen.1)

STG Titanium Exhaust Manifold Stud Kit

Porsche 911 (997) Turbo / GT3 / GT2 – Gen.1

Upgrade one of the most failure-prone fastener sets on the Mezger engine with the STG Titanium Exhaust Manifold Stud Kit, engineered specifically for 997.1 Turbo, GT3 and GT2 models.

Designed for extreme heat cycles, track abuse, and long-term reliability, this kit replaces the factory steel studs with aerospace-grade titanium, eliminating corrosion, reducing weight, and dramatically improving serviceability.

Why Upgrade to Titanium?

Factory exhaust studs are notorious for seizing, snapping, and corroding—especially on high-heat turbocharged and GT applications. STG titanium studs solve this problem at the source.

• Exceptional heat resistance – ideal for turbo and motorsport use

• Corrosion-proof – no rust, no seizure, no snapped studs

• High tensile strength with reduced mass vs OEM steel

• Improved long-term serviceability for future exhaust work

Whether you’re fitting upgraded headers, a performance exhaust system, or refreshing a high-mileage engine, this kit is a must-have reliability upgrade.
