JDC Titanium Exhaust Manifold Stud Kit | Evo 1–9 / 2G DSM

Upgrade your turbo setup with the JDC Titanium Exhaust Manifold Stud Kit, engineered for Mitsubishi Evolution 1–9 and 2G DSM applications. Factory exhaust manifold bolts and studs are prone to stretching, rusting, stripping, or breaking—especially when paired with aftermarket turbo systems and increased heat cycles. This can lead to exhaust leaks, poor sealing, and costly repairs.

The JDC kit replaces the OEM hardware with Ti6Al-4V (Grade 5) titanium studs, delivering superior strength, corrosion resistance, and long-term durability in high-heat environments. Unlike factory steel hardware, titanium will not rust or seize, making future turbo or manifold service significantly easier.

Each stud features an integrated hex key tip, allowing for precise and simple installation using an Allen wrench. This design ensures proper torque application and secure engagement into the cylinder head, providing consistent clamping force for improved exhaust manifold sealing.

Whether you're running a stock turbo or a high-performance aftermarket setup, this titanium stud kit is a smart reliability upgrade for any Evo or DSM build.

What's Included:

  • (2) M10x1.25x45mm Studs, Nuts, & Washers
  • (7) M8x1.25x45mm Studs, Nuts, & Washers

(Optional) Turbo to Manifold Stud Kit:

  • (4) M10x1.25x45mm Studs, Nuts, & Washers
  • Exhaust manifold to head torque specs: 18-22 ft. lbs.
  • A touch of anti-seize is recommended for installation
  • Check the clearance on your manifold before ordering. Some manifolds will have less clearance than others. If you have a manifold with sharp angle bends straight out of the head flange, we recommend using six-point nuts, which will allow you to use an open-end wrench to tighten them. Twelve-point nuts would require a closed-end wrench to tighten and may not have enough room to get on the nut once the studs are in place. Check for clearance before ordering and you shouldn't have any issues.

GR5 Titanium (Grade 5 Titanium) is a premium alloy composed primarily of titanium, with small amounts of aluminum (6%) and vanadium (4%) for added strength and versatility. Renowned for its exceptional strength-to-weight ratio, GR5 Titanium offers superior corrosion resistance, excellent heat tolerance, and remarkable durability. This makes it an ideal material for aerospace, automotive, medical, and high-performance applications, where lightweight strength and longevity are critical. Its ability to be anodized into vibrant colors further enhances its appeal for customization in industries like motorsports and jewelry.
