Flexible Heat Shield 3.5 in x 6.5in Brushed/Onyx

The Flexible Heat Shield 3.5 in x 6.5 in Brushed/Onyx from Design Engineering is a clamp-on exhaust heat shield engineered to protect underbody components, wiring, and fuel systems from radiant engine heat. This woven fiberglass pipe shield combines thermal protection with a brushed carbon fiber finish, making it an effective solution for vehicles running tight engine bays or modified exhaust systems where heat management is critical.

Measuring 3.5 x 6.5 inches, the flexible heat shield accommodates standard exhaust piping while conforming to irregular bends and angles without rigid constraints. The woven fiberglass construction provides reliable thermal insulation while remaining lightweight at 0.33 lbs, minimizing added weight to the vehicle. Installation is straightforward—the clamp-on design requires no welding or permanent modification, and the included trim ring provides a finished appearance. The brushed onyx finish resists discoloration from heat cycling and blends seamlessly with modern underbody aesthetics.

This heat shield is ideal for builders and technicians working on custom exhaust systems, turbo conversions, or restorations where exhaust routing passes near sensitive components. It's particularly valuable in compact engine bay layouts where stock heat protection is inadequate or has been removed during modifications. Whether protecting fuel injector lines, electrical harnesses, or plastic fuel tanks, the Design Engineering heat shield delivers dependable thermal management without requiring permanent installation changes.

Exhaust heat shielding is a foundational consideration in any high-output or modified vehicle build. Radiant heat can degrade fuel lines, melt wiring insulation, and compromise electronic fuel management systems. Flexible clamp-on shields like this one offer a non-invasive approach to thermal management, preserving factory structure while adding critical protection where it matters most.
