Titanium Exhaust Stud Kit for Subaru EJ series (2008-2021)

Engineered for precision and durability, this Titanium Exhaust Manifold Stud Kit is CNC-machined from aerospace-grade Grade 5 Titanium (Ti-6Al-4V)—renowned for its exceptional strength-to-weight ratio, corrosion resistance, and high-temperature performance.

Each stud features an integrated hex key tip, allowing hand-only installation using a standard Allen wrench—eliminating the risk of over-torquing or cross-threading. This design ensures a consistent, leak-free seal and long-term reliability under extreme conditions.

Unlike factory steel hardware that’s prone to rust, corrosion, and failure, this titanium upgrade delivers long-lasting performance in high-heat, high-stress environments—ideal for turbo manifolds and aftermarket header systems.

(6) M10 x 1.25mm x 55mm Grade 5 Titanium Studs (with Allen key tip)

(6) M10 x 1.25mm Titanium 6-point or 12-point Nuts
