The Original Heatmaster – Proven on Professional Race Teams
The Original Heatmaster – Proven on Professional Race Teams
These are the original Heatmaster Shields used by NASCAR teams today, engineered to stop up to 2500°F radiant heat. Designed for high-performance applications, they protect critical components and interior spaces from the harmful effects of exhaust temperatures.
Ideal For:
Ideal For:
Exhaust pipes
Mufflers
Catalytic converters
Y-pipes & collectors
Starter motor protection
Floorboards & interior heat control
Any exhaust “hot spot.”
How It Works
How It Works
Simply measure:
The total length of the area needing protection
Halfway around the top and sides (leave the bottom open)
Leaving the bottom open allows heat to dissipate downward instead of rising into sensitive components.
We install stainless grommets along the long sides for quick, secure mounting using our heavy-duty stainless tie straps.

Why Choose Heatmaster Over Header Wrap?
Why Choose Heatmaster Over Header Wrap?
Unlike traditional header wrap that traps moisture and suffocates exhaust pipes—leading to corrosion and premature failure—Heatmaster Shields:
✔ Reflect radiant heat instead of trapping it
✔ Prevent exhaust burn-through
✔ Protect starters and interiors
✔ Last significantly longer
✔ Remain cool to the touch even when mounted on hot exhaust components
You can safely touch the shield while it’s installed on a hot exhaust system without getting burned.

#08002 C3 Comp Coupe Viper 2500°F Side Exhaust Heat Shields
Size 19″ x 40″ – Set (2) with 10 stainless straps – Stainless
Vipers are very powerful cars and generate a lot of heat. This stainless product is an excellent way to control extreme heat. It has very low heat transference with a high-temperature ceramic inside and will tolerate direct contact with heat sources such as catalytic converters. Its high melting point (3000 plus degrees) and outstanding radiant heat reflection make it the material of choice. In the Viper application, it is intended to wrap tightly around the factory or an aftermarket exhaust system and block the considerable sill heat at its source. The resultant air gap between the shield and sill’s first surface helps as well. This material is commonly used at the highest levels of motor sports and aerospace.

Why Heatmaster Is Different
Why Heatmaster Is Different
Many exhaust shields on the market simply wrap around pipes or mufflers with no internal insulation. Within days, they heat up completely—leaving you with the same overheating problem.
Heatmaster is engineered differently.
3000°F stainless steel outer layer
2500°F ceramic insulation core
Cool-to-the-touch surface — even under extreme heat
Proven performance used by NASCAR teams
You can literally torch the stainless exterior while touching the shield without burning your hand.
Each Heatmaster Shield is constructed with:
Each Heatmaster Shield is constructed with:
.003 stainless steel
Lengthwise line design for strength and flexibility
Evenly spaced grommets on both long sides
Designed for installation with stainless tie straps
This design reduces extreme radiant heat to vehicle interiors and critical mechanical components.
How to Properly Measure Your Heatmaster Shield
How to Properly Measure Your Heatmaster Shield
To ensure correct performance and heat control:
Measure the total length of the area you need to protect.
Measure the width needed to cover:
The top of the pipe
Halfway down both sides
Leave the bottom open.
Why Leave the Bottom Open?
Why Leave the Bottom Open?
Heat must escape downward.
If heat is trapped, it can:
Build up excessively
Damage or destroy exhaust components
Push heat upward into starters, wiring, or interior areas
By covering the top and sides only, you redirect radiant heat away from sensitive components while allowing safe dissipation below.
What We Need to Process Your Order
✔ Length
✔ Width
Grommets are installed on both long sides and evenly spaced for easy mounting.
