AFE 49-42005 LARGE BORE-HD 4" 409 STAINLESS STEEL CAT-BACK EXHAUST SYSTEM FOR 03-04 CUMMINS 5.9L

The AFE 49-42005 Large Bore-HD 4" 409 Stainless Steel Cat-Back Exhaust System is a sophisticated upgrade designed specifically for Dodge Diesel Trucks from 2003 to 2004 equipped with the robust L6-5.9L Cummins engine. Crafted from mandrel bent 4" 409 stainless steel tubing, this heavy-duty exhaust system guarantees maximum airflow, leading to enhanced horsepower and torque while effectively lowering exhaust gas temperatures (EGTs).

Designed for both performance and practicality, the system features a complete kit that includes a 4" cat-back exhaust with a muffler, a muffler delete pipe for those seeking a race-inspired experience, and an elegantly polished tip. The focus on seamless installation is evident; every system utilizes the factory mounting locations, ensuring a stable fit and simplifying the setup process.

An important aspect of the design is the leak-free seals created by high-quality OE style band clamps, ensuring a complete 360-degree sealing surface for optimal performance. The 24" long muffler efficiently absorbs high-pitch sounds, delivering an aggressive tone while maximizing the engine's power output. For enthusiasts desiring more raw power, the included muffler delete pipe enhances the auditory experience significantly.

Engineered with OE style bayonet hangers, this exhaust system achieves a perfect fit. These hangers offer stability during high vibrations and heat, maintaining their integrity over time. With smooth transition bends that reduce turbulence, the Large Bore-HD exhaust system promotes increased horsepower and torque, making it the ideal choice for any serious diesel truck owner.

Manufactured in Corona, California, this exhaust system complements the 2003-2004 Dodge RAM Heavy Duty 2500 and 3500 trucks. Designed for durability, performance, and ease of installation, the AFE 49-42005 is the ultimate choice for those looking to elevate their truck’s capabilities.

The new Large Bore-HD exhaust is engineered to perform in the most extreme environments. This system is constructed from mandrel bent 4" 409 stainless steel tubing for maximum flow, increased horsepower, increased torque and lower EGT's. This system is available in 4" cat-back with muffler, muffler delete pipe and a polished tip. Large Bore-HD exhaust systems are the perfect combination of performance, fit and value.
