The Dodge Challenger Scat Pack is the undisputed heavyweight champion of the modern muscle world. Powered by the legendary 392 cubic-inch HEMI V8, it delivers 485 horsepower and 475 lb-ft of torque straight from the factory. For many, that is plenty. But you are not "many." You are looking for more. You want more aggression, better throttle response, and a presence that stops traffic.

At DTX Performance, we specialize in "Modern Muscle." We know that the Scat Pack is a precision machine that responds incredibly well to the right modifications. Whether you are aiming to dominate the drag strip or simply want the loudest, cleanest-sounding cold start in your neighborhood, selecting the right parts is critical.

Push your build further. Select high-performance components. Shop with confidence. Here is our expert guide to the best performance mods for your Dodge Challenger Scat Pack.

Breath Power: High-Flow Cold Air Intakes

Performance starts with oxygen. The stock airbox on the 6.4L HEMI is functional, but it is designed for the average consumer: not the enthusiast. To unlock the mid-range pull and sharpen your throttle response, a Cold Air Intake (CAI) is the essential first step.

A high-quality CAI replaces the restrictive factory tubing and filter with a high-flow element and a smoother intake tract. This allows a larger volume of cooler, denser air to enter the engine. In the world of naturally aspirated engines, cooler air equals more power. You can expect gains of 5–15 horsepower and a significantly more aggressive intake growl under wide-open throttle.

When selecting an intake for your Scat Pack, look for systems that include a heat shield or a closed-box design. The engine bay of a Challenger gets incredibly hot; you want to ensure your intake is pulling air from the fender well or the "Air Catcher" headlamp, not the hot air surrounding the engine block.

Rule the Sound: Exhaust System Upgrades

The 6.4L HEMI has one of the best exhaust notes in automotive history, but the factory active exhaust system can feel a bit muffled. If you want to announce your arrival, an exhaust upgrade is non-negotiable.

Borla vs. Corsa: The Great Debate

For the Scat Pack enthusiast, the choice often comes down to two titans: Borla and Corsa. Both offer premium T304 stainless steel construction, but they provide very different acoustic profiles.

• Borla (ATAK Series): If you want a deep, throaty, "old-school" muscle car rumble, Borla is the choice. The ATAK (Abnormally Tuned Aggressive Keystates) technology is designed for maximum volume without sacrificing clarity.
• Corsa (Extreme Series): Corsa is famous for its "Reflective Sound Cancellation" (RSC) technology. This provides a high-pitched, exotic-sounding scream at high RPMs while guaranteeing zero cabin drone during highway cruising.

For those looking for a track-ready setup that cuts weight and maximizes flow, consider the AWE Tuning 2015 Dodge Charger 6.4L/6.2L Track Edition Exhaust. While designed for the Charger, the engineering principles behind AWE’s 180 Technology apply directly to the high-performance demands of the Scat Pack platform, offering a raw, unfiltered exhaust experience.

American Racing Headers: The Power Play

If you are serious about horsepower, cat-back exhausts are only half the story. To truly unlock the 392, you need Long Tube Headers. American Racing Headers (ARH) is the industry standard for the HEMI platform. By replacing the restrictive factory manifolds with long-tube headers, you improve exhaust scavenging, pulling spent gases out of the combustion chamber more efficiently. Combined with a proper tune, ARH headers can add 20–30 horsepower and a level of volume that is truly earth-shaking.

Control the Brain: ECU Tuning and Gauges

The hardware is only as good as the software controlling it. Modern Mopar ECUs are notoriously locked from the factory, but bypassing this is the key to massive gains.

Unlocking Potential

An ECU tune optimizes ignition timing, adjusts air-fuel ratios, and redefines throttle mapping. On a Scat Pack, a 93-octane tune can provide an immediate 20–50 horsepower boost, especially when paired with an intake and headers. It also allows you to adjust fan settings to keep the engine cooler and modify transmission shift points for crisper, faster gear changes.

Precision Monitoring: Gauges

As you push your vehicle harder, monitoring its vitals becomes a priority. While the factory "Performance Pages" are excellent, professional-grade gauges provide real-time data with higher accuracy.

• Wideband Air/Fuel Ratio Gauges: Essential for tuned cars to ensure the engine isn't running lean.
• Oil Pressure and Temperature: Critical for track days to prevent engine failure.
• Boost Gauges: If you plan on adding a supercharger in the future, a boost gauge is a mandatory addition to your pillar pod.

Command the Road: Suspension Upgrades

The Challenger is a heavy car. From the factory, the Scat Pack handles well for its size, but there is significant room for improvement in cornering and stance.

Lowering Springs and Coilovers

A set of high-performance lowering springs will drop the center of gravity, reducing body roll and giving the Challenger that aggressive, tucked look every enthusiast craves. For those who want total control over ride height and damping, coilovers are the ultimate solution. They allow you to dial in your suspension for the street or the strip, ensuring that 485 horsepower actually makes it to the pavement.

Sway Bars and Strut Tower Braces

To eliminate the "boat-like" feeling in tight corners, upgrade your sway bars. Thicker, stiffer bars reduce lateral body roll significantly. Adding a front and rear strut tower brace will further stiffen the chassis, improving steering precision and making the car feel more connected to the driver.

Supporting Mods: The Essentials

You can't build a high-performance machine without focusing on the details. These "supporting mods" ensure your Scat Pack stays healthy and handles the extra power.

Oil Catch Cans

The HEMI engine is prone to oil vapor blow-by, which can enter the intake manifold and coat your valves, leading to carbon buildup and reduced performance. An oil catch can is a simple, effective mod that "catches" this oil before it enters the engine. It is cheap insurance for the longevity of your 392.

Wider Rubber

Power is useless if you're just spinning your tires. The stock 245mm or 275mm tires are often the weakest link in a Scat Pack. Upgrading to a 305mm or 315mm rear tire will dramatically improve your 0-60 times and give the car a wider, more menacing footprint.
