JDC Titanium Exhaust Manifold Stud Kit (Evo X)

Using the factory exhaust manifold bolts and studs with an aftermarket turbo 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 Ti6Al-4V (Grade 5) titanium and incorporates a hex key tip that allows them to be easily installed using an Allen wrench.

Torque Specs:

  • Exhaust manifold to head: 37 ft-lbs + or - 3 ft-lbs.
  • Turbo to manifold: 22ft-lbs + or - 1ft-lb.

Note:

  • Please 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.

Beautiful pieces, amazing quality

The unthreaded tip really helps to get a nut started and the threads cut into the bolts and nuts are perfection. Tight tolerances and smooth threading! I will caution against the 12-point nuts if you have a tight tolerance between your manifold and head/turbo.

Do these clear the corners of the map manifold for Evo X

JD Customs U.S.A

Yes, they do. We've sold thousands of these kits and they should work perfectly with the MAP Manifolds.

Do the washers clear the MaPerformance cast manifold?

JD Customs U.S.A

They do. I would recomment using the 6-point nuts with that manifold as well.

How Do I Keep My Titanium Products Looking Brand New?

Installing: Wear gloves when installing titanium parts to prevent oils from your hands causing a "faded" look. After installation, clean the part before applying heat to avoid baking oils onto the surface.

Cleaning: Use our JDC Titanium Cleaner, designed to safely clean titanium without damaging the finish. Alternatively, clean with soapy water, a microfiber towel, or Windex, rubbing alcohol, or Clorox wipes.

Avoid: Harsh chemicals like water spot remover, engine degreaser, brake cleaner, metal polish, or acidic cleaners—they can damage the oxidized layer and remove the color.

Tip: Always clean when parts are cool to avoid water spots or tarnished finishes.
