Titanium stud and nut kit, exhaust maifold to head. Porsche 718 GT4 RS / Spyder RS

• Porsche Boxster Spyder RS 718 4.0L 
• Porsche Cayman GT4 RS 718 4.0L

This premium cylinder head to manifold titanium stud and nut kit is the ultimate solution for future-proofing your exhaust system. Manufactured from Grade 5 Ti6Al4V titanium, these fasteners offer exceptional strength comparable to steel while delivering an impressive 40% weight reduction. Titanium also provides natural corrosion resistance, ensuring the studs and nuts will not rust, seize or degrade even after repeated heat cycles and long-term exposure to extreme engine bay conditions.

Perfect for performance upgrades, engine rebuilds, exhaust overhauls or preventative maintenance, this titanium stud kit guarantees reliability, serviceability and long-lasting durability.

What Titanium Cylinder Head to Manifold Studs & Nuts Do

These titanium fasteners play a crucial role in exhaust system performance and reliability:

• Secure the exhaust manifold to the cylinder head under high heat and vibration
  
• Maintain consistent clamping force, preventing exhaust leaks
  
• Provide excellent thermal stability, resisting heat cycling fatigue
  
• Reduce overall hardware weight, improving performance and serviceability
  
• Prevent corrosion, avoiding seized or snapped studs during future maintenance
  
• Support performance exhaust systems with high-strength, precision-threaded hardware

This kit delivers superior fastening strength and long-term exhaust sealing.

Why Standard Exhaust Studs Commonly Fail

Conventional steel exhaust studs operate in harsh environments where heat, moisture and vibration accelerate deterioration. Common failure causes include:

• Rust and corrosion, especially in older or high-mileage vehicles
  
• Stud seizure, making removal extremely difficult
  
• Thermal expansion fatigue, weakening the metal over time
  
• Shearing or snapping, often during exhaust servicing
  
• Material degradation from repeated heat cycles
  
• Exposure to salt and moisture, especially in winter climates

These failures can lead to exhaust leaks, poor performance, broken studs in the cylinder head and costly repair work.

Why You Should Replace Them with Titanium Studs & Nuts

Switching to high-grade titanium fasteners ensures exceptional long-term performance and eliminates common exhaust hardware issues.

Key benefits include:

• Rust-proof performance, even after years of heat cycling
  
• As strong as steel but 40% lighter thanks to Ti6Al4V alloy construction
  
• Reduced risk of stud seizure, making future exhaust removal easier
  
• Improved durability, especially on tuned or high-temperature engines
  
• Enhanced thermal stability, maintaining clamping force under extreme heat
  
• Ideal for performance exhaust systems, turbocharged engines and track-driven vehicles
  
• Future-proofing your engine bay, saving time and money on future repairs

For any rebuild, upgrade or exhaust replacement, these titanium studs are a significant and smart improvement over traditional fasteners.
