The Story
REDBACK Mega Power Megaflow 409 Stainless Truck Muffler Solution for your Vehicle Universal Application
The REDBACK Heavy Duty 409 Stainless Truck Muffler (TR1044500GP-409) is the pinnacle of high-flow exhaust engineering for commercial vehicles. Measuring a massive 44" (1118mm) in length with a 10" round barrel, this muffler is built from high-grade 409 Stainless Steel for superior heat and corrosion resistance. Featuring a straight-through Megaflow internal design with stainless steel mesh wrapping and high-temp fiberglass packing, it is engineered to handle extreme exhaust pressures and temperatures while providing maximum flow for large-bore systems.
Key Features:
- Megaflow Straight-Through Internals – Delivers zero restriction and maximum exhaust gas velocity for heavy-duty engines
