Kill the Bottleneck. Unleash the Beast.
Your engine is an air pump. You spent thousands on cold air intakes, high-flow filters, and tuning, but you’re still choking the exit. Factory exhaust manifolds are designed for one thing: mass production. They are heavy, restrictive cast-iron lumps that prioritize cost over flow. They trap heat, create backpressure, and rob your build of its true potential.
If you want real power: the kind of horsepower you can feel in your chest and hear in the next zip code: you need headers. But not just any headers. You need American Racing Headers (ARH).
At DTX Performance, we don't settle for "good enough." We demand excellence. When it comes to modern muscle: HEMI, LS/LT, and Coyote: ARH is the gold standard.
The Anatomy of Excellence: 304 Stainless Steel
Most budget headers on the market use 409 stainless steel or, worse, aluminized steel. These materials are prone to surface rust, heat fatigue, and eventual failure. ARH utilizes 100% aircraft-grade 304 Stainless Steel.
Why does this matter?
- Corrosion Resistance: 304 stainless contains high levels of chromium and nickel. It will not rust through, even in the harshest environments.
- Heat Management: High-quality stainless handles the extreme temperatures of a forced-induction Hellcat or a high-revving Coyote without warping.
- Longevity: This is a "buy it once" modification. ARH systems are built to outlast the vehicle they are bolted to.
Every ARH system is 100% Made in the USA. From the laser-cut flanges to the hand-merging of the collectors, the craftsmanship is unmatched. When you select ARH, you are supporting American manufacturing and receiving a product engineered for the highest levels of racing.

Long Tube vs. Shorty: The Only Debate That Matters
In the world of exhaust upgrades, you’ll encounter two main configurations: Long Tubes and Shorties. If your goal is maximum performance, the choice is clear.
Shorty Headers
Shorty headers are designed as a direct replacement for factory manifolds. They bolt up to your existing mid-pipes. While they offer a slight improvement in flow and weight reduction over cast iron, they are limited by their length. They provide a better sound, but the horsepower gains are marginal.
Long Tube Headers
This is where the magic happens. Long tube headers feature extended primary tubes that merge into a single collector far downstream. This design utilizes scavenging. As exhaust pulses exit the cylinder, they create a vacuum behind them, literally pulling the next pulse out of the engine.
The Result:
- Massive gains in torque and horsepower across the entire RPM range.
- Significant reduction in backpressure.
- A deeper, more aggressive exhaust note that signifies a true performance build.
For the HEMI, LS, and Coyote platforms, long tubes are the only way to go if you want to see gains of 20, 30, or even 50+ horsepower depending on your supporting mods.
HEMI Power: Dominating the Mopar Landscape
Whether you’re piloting a 6.4L 392 Scat Pack or a 6.2L Supercharged Hellcat, the HEMI engine craves air. The factory manifolds on these cars are notoriously restrictive.
The 392 HEMI (6.4L)
The N/A 392 is a torque monster, but it falls off in the higher RPMs. ARH long tubes transform the power curve. By optimizing exhaust flow, you allow the HEMI to breathe at high speeds, extending your usable power band. Pair these headers with an AWE Tuning 2015 Dodge Charger 6.4L Track Edition Exhaust for a sound profile that is unmatched on the street.
The Hellcat & Redeye (6.2L)
When you’re pushing 11+ psi of boost, exhaust backpressure is the enemy. It creates heat, and heat kills horsepower. ARH headers for the Hellcat platform feature 2" primaries that allow the supercharger to work more efficiently. You aren't just gaining power; you're increasing engine safety by reducing cylinder temperatures.

LS & LT Dominance: The Heart of the GM Performance
From the legendary LS3 to the modern LT1 and LT4, GM’s small-block V8s are the most modified engines on the planet. ARH is so respected in this space that they are the officially licensed header for Chevrolet Performance’s COPO Camaro program.
Camaro SS & ZL1
The 6th Gen Camaro is a precision instrument. Adding ARH long tubes to an LT1 or LT4 engine provides an immediate increase in throttle response. The precision-fit flanges ensure a leak-free seal, which is critical for maintaining accurate O2 sensor readings and fuel trims. If you're running a Camaro SS, consider finishing the system with the AWE Tuning 16-19 Chevrolet Camaro SS Axle-Back Exhaust for a refined yet aggressive tone.
Corvette & CTS-V
For Corvette (C6/C7) and CTS-V owners, space is often the biggest challenge. ARH engineers their headers with tight tolerances to ensure they clear steering shafts and frame rails without the need for "clearancing" (i.e., hitting them with a hammer). You get a bolt-on fit with track-proven results.
The Coyote Screamer: Mustang High-RPM Performance
The Ford 5.0L Coyote engine is unique. It relies on high-RPM airflow to make its power. Because the Coyote features a DOHC (Double OverHead Cam) design, it reacts differently to exhaust pulses than a pushrod engine.
ARH Coyote headers are designed with tuned primary lengths that specifically target the high-RPM nature of the Mustang.
- Torque Recovery: Many large-diameter headers cause a loss of low-end torque. ARH uses sophisticated collector designs to maintain exhaust velocity, ensuring you don't lose that "stoplight-to-stoplight" punch.
- Top-End Rush: Once the Coyote crosses 4,000 RPM, the ARH headers take over, providing a relentless pull all the way to the 7,500+ RPM redline.
Whether you're running a Gen 1, Gen 2, or the latest Gen 3/4 Coyote, ARH offers a variety of primary sizes (1-3/4" to 1-7/8") to match your specific build goals.

Engineering the Perfect Merge: The ARH Collector
A header is only as good as its collector. The collector is where the four primary tubes meet. If this transition is turbulent, it creates a "logjam" that kills flow.
American Racing Headers utilizes a hand-finished merge collector with an internal "spear." This spear directs the exhaust gases into the center of the collector, preventing turbulence and maximizing the scavenging effect. This attention to detail is why ARH consistently outperforms "eBay headers" and budget brands on the dyno.
