Header Back
Upgrade your vehicle's exhaust with a header-back system—a complete replacement from the headers to the tailpipe. Designed to reduce restriction and improve flow, header-back kits replace the factory mid-pipes, resonators, mufflers, and tailpipes with larger-diameter, mandrel-bent tubing and high-flow components. This unlocks deeper exhaust note, reduced backpressure, and often measurable horsepower and torque gains, especially on tuned engines.
Key features to consider when choosing a header-back system:
- Material: 304 stainless steel offers corrosion resistance and longevity; aluminized steel provides a budget-friendly option.
- Diameter: Larger tubing (e.g., 2.5", 3") supports higher horsepower but may affect low-end torque; match to your power goals.
- Sound: Designs range from mild (resonated) to aggressive (straight-through); many include adjustable or removable mufflers.
- Installation: Most systems bolt to factory mounting points and include necessary clamps, gaskets, and hardware; welding may be required for some.
Browse our collection to find the right header-back exhaust for your application. Whether you're chasing track-ready flow or a refined street sound, we offer systems from trusted brands with precise fitment and durable construction.
