Made from crushed volcanic rock, the Lava Wrap has all the same benefits as exhaust heat wrap with that trick carbon fiber look and improved durability. This exhaust wrap is 25 percent stronger than fiberglass wraps, giving it a prolonged life and greater durability. By wrapping the header and exhaust system, it maintains hotter exhaust gases, decreases the density, and that allows the exhaust gas to exit the system faster. Greater exhaust scavenging is produced helping to lower air intake temperatures. This gives you more horsepower. Volcanic header wrap also reduces radiant heat damage and can lower under hood temperatures by as much as 50 percent. the Lava Wrap withstands 1200F continuous (please note this is a real world tested rating, please don't believe over inflated temperature ratings of similar basalt/volcanic rock products) and 2000F intermittent. Give ythe headers and exhaust system a custom look with the Lava Wrap. the volcanic exhaust wrap can be fastened with Thermal-Tie, hose clamps, or wire.
