Doug’s Headers D523 2″ 4-Tube Full Length
Doug’s Headers D523 is a full-length, 2-inch, 4-tube header set designed for Pontiac Firebird 400-455 models from 1970 to 1974. Its thick flanges (ranging from 3/8 inch to 5/8 inch) help prevent warping during heat cycles. CNC mandrel-bent tubes promote precise fit and improved exhaust flow. A precision-formed long-transition collector further reduces backpressure, supporting enhanced scavenging of exhaust pulses and potential gains in throttle response.
Doug’s Headers D452 2″ 4-Tube Full Length
This Doug’s Headers D452 set targets Mopar B Body big-block applications from 1962-1972. It uses thick flanges (3/8 inch to 5/8 inch) to prevent warping, and CNC mandrel-bent tubes to ensure an accurate fit and superior flow. The long-transition collectors are designed to minimize backpressure, helping to improve exhaust scavenging and overall engine response in classic Mopar builds.
SunplusTrade Heat Wrap 2″ x 50′ (Motorcycle/Car)
SunplusTrade offers a 2-inch by 50-foot heat wrap kit with stainless steel locking zip ties (12-inch). The wrap withstands up to 1400°F direct and 2000°F radiant heat, providing strong thermal insulation. Its resistance to abrasion and oil spills makes it a practical choice for maintaining under-hood temperatures, reducing heat soak, and potentially protecting nearby wiring and components.
SunplusTrade Titanium Exhaust Wrap 2″x50′
This titanium exhaust wrap uses premium volcanic rock fiber for heat reduction and a distinctive carbon-like finish. The package includes six 12-inch locking zip ties and is rated to withstand up to 1400°F direct heat and 2000°F radiant heat. It is designed for exhaust headers and other heat-intensive components, offering robust resistance to abrasion, oil spills, and vibration.
JBA 1949S 1-1/2″ Shorty Stainless
The JBA 1949S shorty header is a stainless steel mandrel-bent design featuring a patented Firecone collector and extra-thick collector domes. This configuration aims to deliver improved exhaust flow in tight-engine bays, with durability and corrosion resistance inherent to stainless steel. It is suitable for Dodge 4.7L Dakota/Durango models from 2000-2003, providing a balance of performance gains and ease of installation.
Doug’s Headers D930-B Black Sidemount
The D930-B Black Sidemount from Doug’s Headers features thick flanges (3/8 to 5/8 inch) to resist warping and CNC mandrel-bent tubes for precise fitting and improved flow. Its long-transition collectors are designed to reduce backpressure, aiding exhaust scavenging and potentially increasing horsepower and throttle response in compatible cars with sidemount configurations.
Deecam Heat Wrap Roll 2″ x 16.5′
Deecam’s 2″ x 16.5′ exhaust heat wrap uses basalt fibers to deliver high-temperature insulation with a carbon-like appearance. It effectively blocks exhaust heat from causing under-hood temperature rises, reducing heat exposure to cables and hoses. The wrap offers good heat dissipation, contributing to engine performance stability and potential longevity of related components, with notable abrasion and vibration resistance.
Buying Guide: Key Purchase Considerations
- Vehicle compatibility: Verify engine type, exhaust manifold configuration, and available space before selecting headers. Shorty headers fit tighter engine bays, while full-length designs optimize flow on larger builds.
- Header material and finish: Stainless steel and ceramic-coated options resist corrosion and heat, extending service life in daily drivers and performance cars alike.
- Flange thickness and fit: Thicker flanges reduce warping under heat cycles; ensure bolt patterns and flange dimensions match your exhaust manifold and collector.
- Flow characteristics: Long-transition collectors and CNC mandrel-bent tubes typically reduce backpressure and improve scavenging, translating to better throttle response and potential horsepower gains.
- Accessory compatibility: If using heat wraps, confirm length, width, and tie-down method. Some wraps pair well with heat shields or ceramic coatings for maximum temperature control.
- Installation considerations: Some headers require modifications or additional gaskets. Consider professional installation if you are not experienced with exhaust work.
- Maintenance and warranties: Check warranty length and coverage for headers and related components. Stainless steel products may offer longer protection in corrosive environments.
These options cover a range of goals, from raw performance to thermal management. When selecting, balance fitment, material quality, and intended use—street, strip, or mixed-performance builds—to achieve the best overall outcome for your car.
