HIFROM Aftermarket Muffler Exhaust WT Cover Replacement for Stihl 029 MS290 039 MS390 MS310 Chainsaw New

Bought it to mod, very heavy metal. Nicer than the factory. Fit ms390 perfectly.

Was a direct fit and worked perfectly on my ms 310.

Buy with confidence. This is at least as good as OEM.I've bought others with thinner metal but they fall apart after enough heat cycles. This muffler is very well made with heavier thicker metal.

This muffler seems to be made a cut above the rest of its cheapo competition.

Fits Stihl MS310 but no screen included with the kit - strange why they omitted that part. Just use the old one. Looks a little different on the front - 2 extra holes. Doesn’t seem to affect throttle response or anything else.

I like that it fit an works

It works great.easy to replace. Would buy it again.

Used this muffler to mod and kept my original as a spare. A little tuning and a sharp chain is all it took to wake my saw up. My MS 290 feels like a beast compared to before!
