This is a **OEM** Husqvarna 372 / 385 / 390 Dual port muffler with screens intact. The West Coast Saw universal exhaust port is bolted to the muffler via the 2x 8-32 socket head cap screws. This allows you to service the spark screen as needed. A 3/4” hole under the universal port offers great flow and a nice sound while in use.
**This is for the Husqvarna OEM 372xp Muffler**
**You need to re-tune your saw after installing this muffler on your chainsaw**
