RISON TITANIUM Pro-Series – M10x1.25 Titanium Exhaust & Turbo Stud Kit (12-Piece Set)
Eliminate the nightmare of rusted, brittle, and snapped factory steel studs. Precision-machined for high-performance Japanese import engines and heavy-duty turbochargers, this 12-piece premium kit is engineered from Aerospace-Grade GR5 (Ti-6Al-4V) Titanium.
The M10x1.25 fine thread pitch operates in the absolute harshest thermal environments. OEM steel hardware constantly heat-cycles, leading to hardware stretching, scaling, and eventual exhaust leaks or warped flanges. RISON Titanium studs maintain immense tensile strength at glowing track temperatures, giving you permanent, worry-free clamping force that never rusts, seizes, or snaps inside your block.
Choose Your Length Based on Your Exact Setup:
-
45mm Standard Length (OEM Replacement): The absolute correct length for factory exhaust manifolds, standard-thickness aftermarket headers, and JDM OEM replacements.
-
54mm Extended Length (High-Performance Cast/Turbo Upgrades): The essential choice when upgrading to extra-thick investment-cast exhaust manifolds, heavy-duty turbo adapter flanges, or high-performance aftermarket turbo downpipes/drop-pipes where longer thread engagement is required to prevent thread stripping.

Exact Fitment & Length Guide (M10x1.25 Only)
Please verify your runner thread and total flange thickness. This kit is strictly confirmed for:
-
Mitsubishi Lancer Evolution I-IX (4G63T) & EVO X (4B11T):
-
45mm fits OEM/standard exhaust manifolds and factory turbo-to-manifold connections.
-
54mm fits extra-thick aftermarket tubular or investment-cast exhaust manifolds.
-
Toyota Supra / Custom JDM Builds:
-
45mm is the ideal direct replacement for the factory cylinder head exhaust manifold runners (1JZ-GTE / 2JZ-GTE).
-
Nissan GT-R / Silvia (RB26DETT / SR20DET / VG30DETT):
-
45mm/54mm fits the turbocharger turbine housing outlet to the aftermarket Downpipe/Dump Pipe flange (verify factory backing-space depth).
-
Honda K-Series (K20/K24 Turbo Upgrades):
-
54mm fits aftermarket turbo-to-downpipe connections utilizing thicker performance flanges.
Why GR5 Titanium is Essential for High-Heat Zones
-
Anti-Seize & Rustproof: Exhaust components regularly exceed 1000°F. Steel scales and fuses into aluminum cylinder heads. RISON Titanium is 100% corrosion-resistant, ensuring effortless removal even after years of hard tracking.
-
No More Exhaust Ticks: Precision rolled threads handle massive stress without deforming, stretching, or backing out, sealing your gaskets flawlessly under high boost.
-
45% Lighter Than Steel: Drops weight from the upper block while cleaning up your engine bay aesthetics.
Premium Finish Options (11 Styles Available)
-
Mechanical & Clean: Titanium Raw
-
Hand-Torched Gradients: Burnt Blue (Hand-Torched)
-
Mirror Smooth PVD: Gold, Black, Rainbow, PVD Burnt Blue

Essential Installation Guide
-
Prep the Threads: Always clean engine holes with an M10x1.25 thread chaser and brake cleaner to remove carbon crust.
-
Apply Anti-Seize: Apply a high-quality nickel-based anti-seize to the block side only. Never use copper anti-seize (risks galvanic reaction with titanium).
-
Hand Thread Only: Screw studs into the head by hand until snug. Do not use impact guns.
-
Torque & Check: Torque to factory specs using a calibrated wrench. Re-verify torque after the first heat cycle.
