Design Engineering Black Titanium Exhaust Heat Wrap — Lava Rock Technology, 1800°F Resistance

Design Engineering's Black Titanium Exhaust Heat Wrap is a lava-rock-based high-temperature wrap engineered to cut radiant under-hood heat and keep exhaust gases hotter for improved flow and component protection.

Wraps for exhaust plumbing do more than look tidy: they reduce radiated heat, protect surrounding components, and help maintain exhaust gas velocity for better scavenging. DEI's Black Titanium wrap uses pulverized lava rock fibers woven into a dense, fire-resistant cloth that tolerates extreme temperatures and stands up to chemicals, oil, and vibration. Manufactured in the USA with three decades of heat- and sound-control engineering, this wrap is built for demanding automotive, marine, powersports, and industrial applications.

How does this wrap lower under-hood temperatures?

The dense lava-rock fiber construction blocks and reflects radiant heat away from nearby parts, cutting thermal transfer through hoods and firewall openings. By containing heat within the exhaust path, it reduces the amount of heat soaking into intake systems and wiring, helping maintain cooler operating conditions for sensitive components.

• Reduces radiant under-hood heat by up to 50%.
• Limits heat soak into intake air and electronics.
• Shields firewall and floor from excessive heat transfer.

Will it stand up to extreme engine temperatures and harsh conditions?

Yes — the lava rock fiber weave resists continuous direct heat up to 1800°F and can tolerate intermittent spikes up to 2500°F. The material also resists damage from oil, chemicals, and vibration, so it lasts longer than typical fiberglass wraps in real-world environments.

• Continuous direct heat resistance: 1800°F.
• Intermittent spike tolerance: 2500°F.
• Chemical- and oil-resistant for extended service life.

How easy is it to install and fit around bends and flanges?

DEI's proprietary tight weave and flexible fiber construction make the wrap pliable enough to conform around tight bends, headers, and complex manifolds. Installation is typically performed with stainless clamps, ties, or adhesive where specified, and the wrap trims cleanly for a custom fit.

• Proprietary weave conforms around curves and elbows.
• Trim- and clamp-friendly for secure mounting.
• Works with common fastening methods for professional results.

What practical benefits can I expect after wrapping my exhaust?

By keeping exhaust gases hotter inside the pipes, the wrap helps maintain higher gas velocity and improves scavenging efficiency in many systems. The result is reduced intake air temperature, less heat-related horsepower loss, and better protection for nearby components and occupants from heat exposure.

• Helps preserve exhaust gas velocity for improved flow.
• Lower intake air temps and reduced horsepower loss from heat.
• Protects wiring, sensors, and bodywork from radiant heat damage.

Who is this for? Install DEI's Black Titanium Exhaust Heat Wrap if you need rugged, long-lasting heat control: performance tuners seeking reduced intake temperatures, off-road and marine users exposed to high-load heat cycles, fabricators building custom exhaust systems, and technicians protecting wiring or cabin areas from heat. It’s intended for professional and enthusiast use on headers, downpipes, exhaust manifolds, and other high-temperature plumbing where durable thermal protection matters.
