Titanium 4in Exhaust Sleeve 12in

The Titanium 4in Exhaust Sleeve 12in from DESIGN ENGINEERING (MPN 10038) is a professional-grade thermal protection wrap engineered for exhaust systems where heat management and durability matter. Built for mechanics and enthusiasts who understand that uncontrolled exhaust heat damages surrounding components—fuel lines, wiring harnesses, underbody trim, and engine bay plastics—this titanium exhaust sleeve creates a thermal barrier that reduces radiant heat transfer while maintaining a clean, finished appearance under your vehicle. Whether you're upgrading a stock exhaust, installing a high-performance header, or rebuilding after engine work, this 12-inch section addresses critical heat zones where standard wrapping alone falls short.

Constructed from woven fiberglass with a titanium-reflective exterior finish, the Titanium 4in Exhaust Sleeve delivers superior heat dissipation compared to traditional cloth wraps. The 4-inch diameter accommodates most single and dual-wall exhaust pipes, while the 12-inch length provides coverage for high-heat transition zones, bends, or collector areas where temperatures spike. Stainless steel ties and installation tools included mean no trip to the hardware store—simply wrap, secure, and tighten. The gray titanium finish resists UV degradation and maintains appearance over years of use, making it ideal for both show-quality builds and daily-driver reliability upgrades where form and function align.

This exhaust sleeve performs best on 4-inch diameter pipes found in aftermarket headers, mid-pipes, and downpipes across muscle cars, turbocharged platforms, and performance trucks. Installation is straightforward: measure your target section, wrap snugly without gaps, and cinch the included ties at 3–4 inch intervals for even pressure. For maximum thermal protection, pair multiple 12-inch sections to cover full header tubes or catalytic converter housings. The compact 0.75 lb weight adds negligible mass, while the robust fiberglass core withstands continuous exhaust temperatures without degradation, making this a one-time investment in engine bay protection and underbody preservation.
