Extreme Duty Offset/Offset 5" Round Resonator Muffler

Exhaust drone on a long highway stint wears you down, that constant boom in the cabin. This straight-through resonator smooths out the tone and knocks back the drone while keeping the gases flowing freely.

Made in Australia from 304 stainless with thick flange plates, it stands up to heavy-duty and off road use, and Redback backs it with a 10-year warranty.

This is a modular offset/offset component that fits into Redback exhaust systems. Check that it matches your setup before ordering.

• Muffler type: 5″ round straight‑through resonator muffler, straight‑flow design.

• Configuration: Offset/Offset (flange alignment for compatibility with offset‑exit exhaust layouts).

• Body material: 304 stainless steel — for corrosion resistance and durability.

• Flanges: 4‑bolt, 10 mm thick flange plates — for secure, vibration‑resistant mounting.
