I installed on my echo cs355t chainsaw.
It sounds awesome and there is a noticeable power gain.
I'll definitely be ordering a few more for our other 355t saws
I’m a part-time cutter. I just added a 462 C-M to the mix. I didn’t even run it stock because I know what a difference adding the EPS Straight Shot makes. Ran it in oak timber and it is super responsive and has a lot of snap to it. I run EPS on 8-10 saws now ranging from an 036 to a 661. Outstanding upgrade that only takes a few minutes to bolt on.
