Description
Overview
The Flowmaster 50 Series HD Chambered Muffler is engineered specifically for today’s heavy duty gas and diesel trucks, delivering improved performance, sharper throttle response and better mileage from a proven chambered design. Built to handle the demands of hard-working rigs, it strikes an ideal balance between an aggressive presence under load and comfortable, livable sound during everyday driving.
Flowmaster’s 50 Series HD is tuned to produce a deeper, moderate tone with minimal resonance, making it a smart match for trucks running modified engines. You get a purposeful exhaust note that lets everyone know your truck means business without the interior drone that can make long highway miles fatiguing.
Built to Last
Durability is central to this muffler’s construction. It’s built from rugged 16 gauge aluminized steel and fully MIG welded throughout, so it can stand up to the heat, vibration and long-haul abuse that comes with heavy duty gas and diesel truck use. The high-temperature paint finish adds protection and helps the muffler look the part underneath your truck.
With a 3.50-inch inlet diameter, the 50 Series HD is sized for the airflow demands of larger displacement and modified powerplants, helping your exhaust breathe while keeping sound at a moderate, refined level. Its chambered internals do the acoustic work, taming resonance while preserving the deep, confident tone the 50 Series line is known for.
Universal Fitment & Installation
This is a universal-fit muffler, giving you the flexibility to integrate it into a wide range of exhaust configurations. It’s designed to use new hangers (not included), so plan on the appropriate mounting hardware for your setup. Exhaust tips are sold separately, allowing you to finish the system exactly the way you want.
