JDC Titanium Exhaust Manifold Stud Kit

Using the factory exhaust manifold bolts and studs can result in stripped or broken bolts and inadequate sealing force, which will result in an exhaust leak. This kit will allow you to properly seal the exhaust manifold to the cylinder head and will never rust or corrode! The JDC titanium stud kit is made from a Ti6Al-4V (Grade 5) titanium and incorporates a hex key tip that allows them to be easily installed using an Allen wrench.

    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.
