Construction & Design:
The aFe Large Bore HD exhaust system is crafted from durable 409 stainless steel tubing, known for its excellent resistance to corrosion and heat. The mandrel-bent tubing ensures smooth, unrestricted exhaust flow, which helps improve engine efficiency and longevity. The system’s OE-style bayonet hangers replicate factory mounting points, providing a stable and secure fit that resists movement and wear over time. The 5-inch black stainless steel slash-cut tip with intercooling vents not only enhances the truck’s appearance but also helps dissipate heat, reducing exhaust gas temperatures at the outlet for improved thermal management.
Performance & Sound
This DPF-back exhaust system is engineered to increase horsepower and torque by reducing exhaust backpressure and improving flow dynamics. The smooth mandrel bends and large bore tubing minimize turbulence, which can lower exhaust gas temperatures (EGTs) and contribute to better engine performance and efficiency. The intercooling vents on the tip further aid in reducing tailpipe temperatures. The system delivers a refined yet aggressive exhaust note that enhances the driving experience without excessive drone or harshness.
Installation & Fitment:
Installation is straightforward, utilizing all factory mounting locations and OE-style bayonet hangers for a secure, stable fit. The system is designed for Ram 1500 Crew Cab models with 5'7" and 6'4" beds, as well as Quad Cab models with 6'4" beds, covering wheelbases of 140" and 149". Please note that cutting behind the DPF unit is required for installation. The included high-quality band clamps facilitate a tight seal and easy assembly.
