Exhaust wrap kit includes our stainless steel locking ties and easy to follow instruction sheet. Exhaust pipe wrap maintains hotter exhaust gases, decreases the density, and that allows the exhaust gas to exit the system faster! Increased exhaust scavenging is produced helping to lower intake temperatures: that equals more horsepower. Exhaust wrap also reduces radiant heat damage and can lower under hood temperatures by as much as 50 percent. Header heat wrap also keeps heat out of the drivers compartment and reduces heat damage to other components. This exhaust wrap features a vermiculite coating which makes it capable of withstanding 1200F continuous and 2000F intermittent.
