About Design Engineering Inc. (DEI)
Design Engineering Inc. — widely known as DEI — has built a reputation as one of the most trusted names in automotive thermal and acoustic management. For decades, DEI has engineered products that solve two of the most persistent challenges in performance and everyday driving: unwanted heat and unwanted noise. Their catalog spans everything from race-proven exhaust wraps to premium acoustic headliner materials, making them a go-to resource for both professional builders and weekend enthusiasts.
A Heritage of Heat Management Innovation
DEI's roots are firmly planted in the world of motorsport, where controlling underhood and exhaust temperatures isn't just about comfort — it's about performance and reliability. Excess heat robs horsepower, degrades components, and creates safety concerns. DEI addressed this challenge head-on by developing a comprehensive line of thermal barriers, wraps, and shields that are equally at home on the track and on the street.
One of the brand's most popular product families is their Exhaust System Wrap lineup. These wraps help contain exhaust heat within the pipe, reducing radiant heat in the engine bay, improving exhaust scavenging, and protecting nearby components from heat damage. Whether you're building a show car or a dedicated race machine, DEI's exhaust wraps deliver measurable results.
For turbocharged builds, DEI offers a specialized line of Turbocharger Heat Shields designed to protect surrounding components from the extreme temperatures generated by forced-induction systems. These shields are engineered to fit a wide variety of turbo setups and are constructed from DEI's proven heat-reflective materials. Complementing these are their Exhaust Heat Shields, which provide targeted protection for areas where exhaust pipes run close to fuel lines, chassis components, or the passenger compartment.
For complete exhaust system projects, DEI also offers convenient Exhaust System Wrap Kits that bundle everything needed for a full wrap job — making it easier to get consistent, professional results without hunting down individual components.
Acoustic Solutions: The DEI Headliner
Beyond heat, DEI has made a significant mark in the world of acoustic management. Their Headliner products are engineered to reduce road noise, suppress heat transfer into the cabin, and improve the overall driving experience. These materials are popular in custom builds, restorations, and daily drivers alike, offering a straightforward way to dramatically improve cabin comfort.
