Design Engineering Titanium Exhaust Heat Wrap, 2-Pack Lava-Rock Fiber, 1800°F Continuous Thermal Shield

Design Engineering Titanium Exhaust Wrap is a high-temperature lava-rock fiber header and pipe wrap built to cut radiant under-hood heat, preserve exhaust gas velocity, and protect nearby components.

Wraps for headers and exhaust pipes do more than look tidy — they manage heat energy so engines run more efficiently and hot components stay protected. DEI's Titanium Wrap is spun from pulverized lava rock into a tight, diagonal weave that resists higher temperatures and mechanical wear better than conventional glass-fiber wraps. It’s manufactured in the U.S. by Design Engineering, a company with three decades of heat- and sound-control experience, and it’s commonly used by racers, custom builders, motorcyclists, and workshop professionals who need durable thermal protection.

How does this wrap reduce under-hood temperatures?

By insulating the exhaust pipes, the wrap keeps combustion gases hotter inside the tubing so they flow faster and transfer less radiant heat to surrounding parts. That results in lower intake and bay temperatures and reduced heat soak of nearby wiring, hoses, and chassis components.

• Reduces radiant under-hood heat by up to 50% compared with unwrapped pipes.
• Maintains higher exhaust gas velocity for improved scavenging potential.
• Shields heat-sensitive components and decreases firewall heat transfer.

What materials and heat ratings should I expect?

DEI Titanium Wrap is woven from fibers made of pulverized lava rock rather than typical glass fiber, giving it superior thermal tolerance and mechanical strength. It’s rated for continuous direct heat up to approximately 1800°F and intermittent radiant exposure up to roughly 2500°F.

• Constructed from lava-rock-based stranded fiber with a dense diagonal weave.
• Continuous direct heat resistance ~1800°F; intermittent radiant tolerance up to ~2500°F.
• Does not require pre-wetting for installation and resists degradation from vibration and oils.

Will it fit my vehicle and stand up to real-world use?

The wrap was designed to be pliable and easy to form around bends, flanges, and header junctions, making it suitable for cars, trucks, motorcycles, and race applications. Its composition resists chemical exposure and vibration, so it holds up in high-stress environments without fraying or breaking down quickly.

• Highly pliable for tight, secure wrapping around complex header shapes.
• Resistant to oil, chemicals, and fatigue from engine vibration.
• Universal fit—works on single pipes, multi-pipe headers, and motorcycle exhausts.

How does using Titanium Wrap affect performance and maintenance?

By reducing heat soak and lowering intake temperatures, wrapped headers can contribute to improved engine efficiency and potentially better horsepower delivery in tuned applications. The wrap also protects components and interior surfaces, simplifying maintenance by reducing heat-related wear.

• Helps keep intake and bay temperatures lower for more consistent performance.
• Protects wiring, hoses, and nearby parts from premature heat-related failure.
• Durable construction means fewer replacements and long-term reliability.

Who is this for: The DEI Titanium Exhaust Wrap is aimed at performance-minded drivers, racers, custom builders, and motorcycle enthusiasts who need a tough, high-temperature insulation solution. It’s a good choice when you want to reduce radiant heat, protect surrounding components, and maintain exhaust gas velocity without frequent replacement.
