Construction & Design

The Apollo GT exhaust system is crafted from premium 409 stainless steel, known for its excellent corrosion resistance and strength under high heat conditions. The mandrel bending process ensures smooth, unrestricted exhaust flow throughout the system, minimizing turbulence and backpressure. This precision engineering results in improved horsepower and torque gains while maintaining a robust and durable structure.

Polished stainless steel tips not only enhance the visual appeal but also resist discoloration and wear from heat and road elements. The use of OE-style band clamps and bayonet hangers replicates factory mounting methods, ensuring a secure fit that withstands vibration and thermal expansion without loosening or rattling.

Performance & Sound

The Apollo GT Cat-Back system is designed to unleash the full potential of your 5.7L HEMI engine by improving exhaust flow and reducing backpressure. This translates into noticeable gains in horsepower and torque, as well as lower exhaust gas temperatures, which can contribute to better engine longevity and efficiency.

The free-flowing muffler balances sound quality by absorbing high-pitched tones and producing a deep, aggressive exhaust note that enhances the driving experience without being overly loud or droning during highway cruising.

Installation & Fitment

This exhaust system is engineered for a direct bolt-on installation using all factory mounting points, eliminating the need for cutting, welding, or modifications. The OE-style bayonet hangers and band clamps ensure a secure and stable fit, making installation straightforward for professional mechanics and experienced DIYers alike.

Designed specifically for Dodge and RAM 1500 trucks from 2009 through 2024 with the 5.7L HEMI engine, this system guarantees precise fitment and compatibility with stock components.
