Key Features
This exhaust system combines advanced engineering with high-quality materials to optimize your RAM’s performance and sound. Key features include:
- Mandrel bent 4-inch 409 stainless steel tubing for maximum exhaust flow and durability
- DPF-back design to maintain emissions compliance while enhancing performance
- Factory mounting locations for straightforward, bolt-on installation
- High-quality OE-style flange and band clamps providing a complete 360-degree sealing surface
- Free-flowing 24-inch muffler designed to absorb high-pitched tones and produce a deep, powerful sound
- OE-style bayonet hangers that maintain stable pipe positioning under high vibration and heat
- Bayonet tip design to securely hold hanger bushings for a consistent OE-style fit over time
- Constructed to withstand extreme heat and harsh operating conditions
Construction & Design
The aFe Large Bore-HD exhaust system is crafted from premium 409 stainless steel tubing, known for its excellent corrosion resistance and strength under high temperatures. The tubing is mandrel bent to ensure smooth, unrestricted exhaust flow, which helps reduce backpressure and improve engine efficiency.
Every component is engineered to meet or exceed OEM standards. The use of OE-style flanges, clamps, and hangers guarantees a precise fit and long-lasting durability. The bayonet hanger system is specifically designed to hold the exhaust securely in place, preventing sagging or misalignment even under the rigors of heavy-duty use.
Performance & Sound
This exhaust system is designed to unlock the full potential of your 6.7L Cummins engine by improving exhaust flow and lowering exhaust gas temperatures (EGTs). The result is increased horsepower and torque, which translates to better towing capability and overall vehicle responsiveness.
The 24-inch free-flowing muffler effectively reduces high-pitched exhaust tones, delivering a deep, aggressive sound that enhances the driving experience without excessive drone. This balance of performance and sound makes it an excellent choice for enthusiasts who want both power and refinement.
Installation & Fitment
The aFe Large Bore-HD exhaust system installs using all factory mounting points, which means no cutting, welding, or modifications are required. The system is designed for a direct bolt-on fit for RAM 2500 and 3500 models from 2007.5 to 2012 with the 6.7L engine, ensuring a straightforward and hassle-free installation process.
OE-style bayonet hangers and clamps simplify alignment and secure the exhaust system firmly in place, maintaining proper clearance and reducing the risk of rattles or vibrations over time.

What does the Available to Promise date mean?
ETA stands for Estimated Time of Arrival. The date shown is calculated using our Available-to-Promise (ATP) system, which tracks real-time supplier commitments to determine when a product is expected to be available for delivery. Specifically, the date is calculated by adding 9 business days from the date a supplier has committed to ship the product, representing a worst-case scenario for when we can expect to receive inventory.
Please note: The ETA is an estimate, not a guarantee. While we work closely with our suppliers to keep dates as accurate as possible, delays due to shipping carriers, weather, customs, or supplier-side issues may occasionally push the actual arrival beyond the date shown. Likewise, inventory may arrive sooner than the ETA in many cases. If you would like to be notified for when this item arrives, sign up for our back in stock notifications!
