Heat is Energy — Don't Waste It
Aerospace-grade silica felt insulation. Not an option — part of the design.
The Problem
Exhaust gases leave the engine at over 800°C. Without insulation, they transfer heat to nearby components — damaging wires, plastics, reducing performance. And they lose velocity.
Dispersed heat = lost energy
Contained heat = maintained velocity
The Lettieri Solution
We wrap every manifold and downpipe with aerospace-grade silica felt insulation. Heat stays in the exhaust stream: gases flow faster, power increases, components are protected.
The Numbers
40%
Heat reduction
Up to 40% reduction in dispersed heat
+HP
More power
Faster gases = more scavenging = more power
1200°C
Protection
Component protection up to 1200°C
