DEI Glass Fiber Exhaust Wrap with Stainless Steel Ties

DEI Glass Fiber Exhaust Wrap with Stainless Steel Ties Reduce under‑hood heat, improve exhaust flow, and protect performance. DEI Glass Fiber Exhaust Wrap insulates headers and downpipes to lower under-hood temperatures, retain exhaust heat for improved scavenging, and help recover horsepower. Realistic 50% reduction in under-hood temperatures Improves exhaust flow by keeping gases hotter and less dense Withstands extreme temperatures: 1200°F direct / 2000°F radiant Includes stainless steel locking ties for a clean, professional, long-lasting installation Durable construction with added heat retention and factory-style installation guidelines Important usage notes: Do not wrap catalytic converters — overheating can shorten converter life. DEI offers alternative shields such as the Corvette Catalytic Converter Shield or Floor & Tunnel Shield II. Exhaust wrap becomes less flexible after heat cycling; removal is not recommended. Avoid wrapping flex-pipes, flex-joints, or titanium exhaust systems (titanium alloys may become brittle). For titanium, consider DEI flexible heat shields instead. Choose DEI for proven thermal control, professional installation hardware, and materials engineered to protect components and enhance engine performance.
