Built for serious power, heavy towing, and harsh Australian conditions, the GSL Dodge Ram 2500 Exhaust System delivers maximum exhaust flow, long‑term durability, and a strong, clean exhaust note. Designed and manufactured in Australia, this system is ideal for Dodge Ram 2500 owners wanting a premium performance exhaust upgrade. 5" DUMP-BACK EXHAUST - MAXIMUM FLOW & PERFORMANCE Manufactured in‑house from premium 5" 304‑grade stainless steel, this dump‑back exhaust system replaces the factory exhaust from the dump pipe back. The larger‑diameter tubing reduces exhaust restrictions, lowers exhaust gas temperatures (EGTs), and improves throttle response — making it ideal for tuned, towed, or performance‑focused Ram 2500 builds. To ensure a secure, leak‑free connection at the turbo, this system features a precision‑machined billet V‑band flange engineered to suit the OEM sealing face. This design offers superior clamping force and sealing performance compared to factory hardware, even under high boost and heavy load conditions. Developed for Ram 2500s used for towing, touring, or street performance, this system produces a clean, aggressive exhaust note without sounding cheap, tinny, or overbearing. Like all GSL Fab exhaust systems, fitment, strength, and real‑world reliability are built into every bend and weld. 5" DPF BACK EXAHUST - OWM FRIENDLY UPGRADE The 5" DPF‑back exhaust system replaces the exhaust from the factory diesel particulate filter back, retaining the original dump pipe and emissions equipment. This option improves airflow and sound downstream while remaining compatible with factory emissions hardware. Ideal for customers wanting a high‑quality stainless steel Ram 2500 exhaust upgrade without modifying the OEM dump pipe assembly. Both exhaust configurations are built to the same premium standard and are designed to deliver a strong, refined exhaust note with no drone or harsh cabin noise.
