Vibrant Titanium 3-Bolt Flange - 3.50in ID / 4.44in Bolt Hole Center-to-Center / .3125in Thick - Universal Fit
This CNC-machined titanium 3-bolt flange connects 3.50in OD round exhaust tubing in custom performance exhaust systems. It creates secure leak-free seals for turbo downpipes exhaust manifolds and high-flow setups on cars trucks and race vehicles. Titanium builds deliver weight savings with resistance to extreme heat up to 1600°F pressure and corrosion for reliable long-term performance.
Key Features
- Titanium Material: 6AL-4V grade titanium provides high strength-to-weight ratio and corrosion resistance for durability in harsh exhaust environments
- Precise Dimensions: 3.50in inner diameter fits standard 3.5in OD tubing with 4.44in center-to-center bolt spacing and 0.375in bolt holes for exact alignment
- Heavy-Duty Thickness: 0.3125in (5/16in) plate thickness resists high torque and vibration without warping
- 3-Bolt Design: Ensures even clamping pressure for airtight connections that minimize exhaust leaks and improve scavenging efficiency
- Matching Gaskets Available: Use with Vibrant multi-layer graphite gaskets for reliable sealing under boost and repeated heat cycles
