Exhaust System / Air Intake Assembly / Computer Chip Programmer Kit

What Are Exhaust System / Air Intake / Computer Chip Programmer Kits?

For drivers who want to unlock the full potential of their engine in a single upgrade, an exhaust system, air intake assembly, and computer chip programmer kit delivers the most comprehensive path to more power, better torque, and improved fuel efficiency. Rather than purchasing individual components one at a time, these bundled power systems combine three of the most impactful performance upgrades into one cohesive package — engineered to work together from day one.

Each element plays a critical role in the performance equation. A high-flow air intake assembly replaces the restrictive factory airbox, feeding the engine cooler, denser air for more complete combustion. An upgraded exhaust system reduces backpressure and lowers exhaust gas temperatures, allowing spent gases to exit faster and freeing up engine power. The computer chip programmer — often a handheld tuning device — recalibrates the engine's ECU to optimize fuel delivery, timing, and other parameters, ensuring the intake and exhaust upgrades translate into real, measurable gains at the wheels.

Why Buy a Bundled Kit?

The key advantage of a complete power system kit is system-level synergy. When an intake, exhaust, and tuner are designed and tested together by a single manufacturer, the components are calibrated to complement each other rather than work at cross-purposes. This eliminates guesswork, reduces installation time, and typically yields stronger results than mixing and matching parts from different brands. These kits are especially popular among diesel truck owners who tow or haul heavy loads, where extra horsepower and torque have immediate, practical benefits.

When shopping for one of these bundles, consider your vehicle's specific application — daily driving, towing, or performance builds — as well as emissions compliance requirements for your region. Many kits carry CARB (California Air Resources Board) certification, making them street-legal in all 50 states.

Top Brands in Complete Power System Kits

Banks Power is one of the most respected names in diesel performance, with decades of experience engineering complete power systems. Their flagship PowerPack and Big Hoss Bundle kits combine Banks-exclusive intake manifolds, upgraded exhaust, turbo enhancements, and the AutoMind programmer into a single, thoroughly tested package. Banks Power kits are particularly well regarded for applications on Ford Power Stroke, Dodge Cummins, and GM Duramax platforms.

aFe (Advanced FLOW Engineering) brings a broad-spectrum approach to performance upgrades, offering solutions that span from cold air intake systems to free-flowing exhaust and electronic programmers. aFe's bundled kits are engineered to maximize airflow at every stage of the engine's breathing cycle, with each component flow-bench tested and designed for both gasoline and diesel applications.
