- OE-style bayonet hangers ensure a secure, vibration-resistant fit that maintains pipe location under high heat and stress
- Utilizes all factory mounting locations for hassle-free, bolt-on installation
- Massive 5" diameter black stainless steel slash-cut tip with intercooling vents to reduce exhaust gas temperatures at the tailpipe
- Laser-cut aFe POWER logo plate riveted on the tip for a distinctive, aggressive look
- Mandrel bends provide smooth transitions to minimize turbulence and backpressure
- High-quality band clamps included for secure connections
- Designed specifically for Ram 1500 Crew Cab and Quad Cab configurations with various bed lengths and wheelbases
Construction & Design
The aFe Large Bore HD exhaust system is constructed 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 features intercooling vents that not only enhance the truck’s appearance but also help dissipate heat, reducing exhaust gas temperatures at the outlet for improved thermal management and component longevity.
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 lowers exhaust gas temperatures (EGTs) and contributes 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, providing a balanced sound profile suitable for both daily driving and spirited performance.
Installation & Fitment
Installation is straightforward, utilizing all factory mounting locations and OE-style bayonet hangers for a secure, stable fit. This 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.
Included high-quality band clamps facilitate a tight seal and easy assembly, ensuring a hassle-free upgrade that maintains factory mounting integrity.
