DEI Titanium 4in Knit Exhaust Sleeve - 12"

DEI (Design Engineering Inc.) has been producing automotive heat and sound control products for over 25 years, creating thermal wraps, exhaust heat shields, heat blankets, acoustic damping mats, and firewall insulation for performance street cars, race vehicles, and marine applications. DEI products address the heat and noise that performance builds generate, protecting nearby components and improving cabin comfort without adding significant weight.Popular UpgradesDEI Titanium exhaust wrap is the most popular product in the DEI catalog, reducing radiated heat from headers and exhaust pipes to protect nearby fuel and brake lines while also slightly improving exhaust gas velocity by keeping temperature higher in the pipe. DEI Gold Heat Shield is widely used to protect fuel rails, brake lines, and electrical harnesses routed near exhaust manifolds and turbocharger housings. Reflect-A-Gold insulation and EzCool acoustic mats are popular for firewall and floor pan heat and sound reductio...

Exhaust wrap reduces radiant heat from exhaust pipes, lowering under-hood temperatures and protecting nearby wiring, sensors, and rubber components from heat damage. It also retains heat within the exhaust flow, improving scavenging velocity and reducing back pressure in turbocharged applications. Popular Upgrades Frequently purchased exhaust wrap products include DEI titanium exhaust wrap for high-temperature applications, fiberglass wrap for budget-conscious builds, and stainless steel locking ties to secure the wrap at each end. Header and manifold wrap kits are the most popular category. How do I install exhaust wrap correctly? Start by soaking the wrap in water to make it pliable. Wrap tightly and overlap each pass by about half the wrap width. Secure the ends with stainless steel ties or high-temp tape. Run the engine after installation to allow the wrap to cure and any smoke to dissipate, which is normal during the first heat cycle. Does exhaust wrap cause pipes to rust faste...
