MRC Racing Components 2”x45ft Exhaust Header Heat Wrap Insulation Roll

Wrap your headers and keep that heat moving out the exhaust instead of baking everything in your engine bay. The MRC Racing Components 2" x 45ft Exhaust Header Heat Wrap retains exhaust heat inside the headers and manifold, significantly reducing underhood temperatures. Lower engine bay temperatures mean cooler intake air, better performance, and longer life for heat-sensitive components like wiring, hoses, and sensors.

At 45 feet long, this roll provides enough material to wrap a complete set of headers, a turbo manifold, or multiple exhaust components. Built from durable, high-temperature-resistant material that holds up in the most demanding thermal environments.

MRC Racing Exhaust Heat Wrap Features

• 2" Wide x 45ft Long — Enough to wrap a complete header set or turbo manifold
• High-Temperature Resistant — Built to withstand direct exhaust heat
• Reduces Underhood Temperatures — Keeps exhaust heat in the headers and out of the engine bay
• Improves Performance — Cooler intake air and cooler engine bay components
• Maintains Exhaust Gas Velocity — Keeping heat in the headers helps maintain exhaust gas speed for better scavenging
• Universal Fitment — Works on any exhaust header or manifold application

Applications

• Exhaust headers and manifolds
• Turbo manifolds and downpipes
• Exhaust piping in tight engine bays
• Any application where exhaust heat management is critical

Notes

• Sold as a single roll
• Stainless steel zip ties or header wrap wire recommended for securing (sold separately)
• Soaking the wrap in water before application makes it easier to work with and tightens as it dries

Pro Tip: Header wrap does more than just protect other components — it actually helps performance. By keeping the exhaust gases hotter inside the header, the gases move faster, which improves exhaust scavenging and can measurably improve power output. It is one of the cheapest power gains you can make on a naturally aspirated or turbocharged setup.
