aFe Large Bore-HD DPF-Back Exhaust System
2011–2018 Ram 1500, 2019–2024 Ram 1500 Classic V6 3.0L EcoDiesel
49-42065-P
Overview:
The aFe Large Bore-HD 3-inch 409 stainless steel DPF-back exhaust system is engineered for Ram 1500 and Ram 1500 Classic models equipped with the 3.0L EcoDiesel V6 engine from 2011 through 2024. Designed to replace the factory DPF-back section, this exhaust system enhances exhaust flow while maintaining a factory-like fit and finish. Ideal for diesel truck enthusiasts seeking improved performance, durability, and a refined exhaust note without compromising reliability or requiring extensive modifications.
This system is perfect for drivers who want to maximize their Ram’s horsepower and torque output while reducing exhaust gas temperatures, all with a straightforward installation process that utilizes existing factory mounting points.
Key Features:
Built to deliver superior flow and long-lasting performance, the aFe Large Bore-HD DPF-back exhaust system includes:
- Mandrel-bent stainless steel tubing ranging from 3" to 3-1/2" for optimized exhaust flow and minimal turbulence
- OE-style bayonet hangers that secure the exhaust in place during high vibration and heat conditions, ensuring a stable, factory-like fit
- 5-inch diameter polished 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 appearance
- Utilizes all factory mounting locations for a hassle-free installation without the need for custom brackets or welding
- High-quality band clamp included for secure connections and leak-free sealing
- Designed specifically for Ram 1500 and Ram 1500 Classic Crew Cab and Quad Cab models with various bed lengths and wheelbases
- Constructed from durable 409 stainless steel for corrosion resistance and long service life
Construction & Design:
This exhaust system is crafted from premium 409 stainless steel tubing, known for its excellent corrosion resistance and durability under harsh conditions. The tubing is mandrel-bent to maintain consistent diameter throughout bends, ensuring smooth exhaust flow and reducing backpressure. The system’s design incorporates OE-style bayonet hangers that hold the pipe securely in place, preventing movement and wear over time even under high heat and vibration typical of diesel engines.
The polished 5-inch slash-cut tip not only adds a sleek, aggressive look but also features intercooling vents that help lower exhaust gas temperatures at the outlet, contributing to improved thermal management and longevity of exhaust components.
Performance & Sound
By increasing exhaust flow with larger diameter tubing and smooth transition bends, this DPF-back system helps improve horsepower and torque output while lowering exhaust gas temperatures (EGTs). The reduction in EGTs can contribute to better engine efficiency and longevity. The exhaust note is enhanced with a refined, deeper tone that complements the diesel engine’s natural sound without being overly loud or droning.
Installation & Fitment:
The aFe Large Bore-HD DPF-back exhaust system is designed for a direct fit using factory mounting points, making installation straightforward and minimizing the need for additional modifications. However, cutting behind the Diesel Particulate Filter (DPF) unit is required to install this system properly. The included high-quality band clamp and OE-style bayonet hangers ensure a secure, leak-free fit that maintains factory stability and alignment.
This system fits the following Ram 1500 and Ram 1500 Classic models:
- Crew Cab with 5'7" Bed (140" Wheelbase)
- Crew Cab with 6'4" Bed (149" Wheelbase)
- Quad Cab with 6'4" Bed (140" Wheelbase)
- Specific trims including Big Horn, HFE, Laramie, Laramie Limited, Laramie Longhorn, Limited, Lone Star, Outdoorsman, SLT, Sport, Tradesman, Classic Laramie, and Classic SLT from 2011 to 2024
What's Included:
- Large Bore-HD 3" to 3-1/2" mandrel-bent stainless steel DPF-back exhaust pipe
- 5" diameter polished stainless steel slash-cut intercooler tip with laser-cut aFe POWER badge
- OE-style bayonet hangers and hanger bushings
- High-quality band clamp for secure connection
- Installation hardware and instructions
Ideal For:
This exhaust system is ideal for Ram 1500 and Ram 1500 Classic owners who want to enhance their truck’s diesel performance and sound while maintaining a clean, factory-quality installation. It suits enthusiasts looking for improved horsepower, torque, and thermal management without sacrificing durability or requiring complex modifications. Perfect for daily drivers, towing applications, and off-road use where reliability and performance are paramount.
