Full power!

Worth the wait. MS400 converted to RS400. Feels similar to when you get your Super Duty tuned. Saw feels like it woke up! Sounds mean and cuts meaner. Thanks Rip Saw!
Would have appreciated a Ripsaw hat tho! 🧢

Just buy it and wait.

Crazy to think I waited 7 months for a saw but I’m glad I did …worth every penny. Do yourself and your family a favor and buy one.

Yes get one.

I have had my Stihl 400 for a few months now and I do love it. I have a West Coast Muffler, aluminum side cover, and the big West Coast felling dogs. Overall, the completed saw does fill my needs and makes me happy. I Wished it came blacked out. They did fail on the Expedited shipping of a completed order. I do however do remand buying their Ported Chainsaws.

Purchased a 400CM from Ripsaw that got their special treatment. The first time I started it, let’s just say I needed a smoke. It’s makes sweet sweet music. The first cut through oak was like butter. The power is amazing! This saw is perfect. Very happy with the saw. You guys do some amazing work.
