Performance Muffler Kit – Fits Husqvarna 592/585

Aerospace-Grade Performance Exhaust System for Husqvarna 592 and 585 

Engineered for superior power and cooler engine temperatures, this exhaust system is precision-crafted from aerospace-grade materials built to handle the toughest conditions. Proudly made in the USA and backed by a lifetime warranty, it delivers unmatched reliability and durability.

Outlet Direction (Facing Bar or Facing Recoil):Facing Bar means the exhaust outlet points toward the guide bar side of the saw. Facing Recoil means it points toward the pull-start side. This is strictly operator preference and has no effect on performance.
