Went with a west coast saw exhaust on my 2511, and took my 590 to the saw shop near me and got it muffler modded and some port work done. Did a couple test cuts out behind the house, definitely loud! Fun to run though, it really woke them both up.
Take that saw to huskihl if you want a real animal...our XS4910 will out cut our XS362 and just about keep up with the XS400. He did a XS7310 that was 2 sec faster than a XS462 he did.
I put a streight pipe from fleabay on my 590 Echo, it sounds like a dirt bike now. I wear plugs and ear muffs, no cutting before 0900 A.M. or so. With a sharp chain it’s my new favorite saw, cuts like the proverbial hot knife through butter.
My 590 hot quite a bit louder with the muffler nodded, I imagine a full pipe sounds great. I started wearing headphones too and I was impressed it was pretty close to my ms360 stock but now ported it really eats. Great saws for the price! Mines been through a lot of cutting in 4 years and its my go to
The 590 responds well to mods. The aftermarkey air filters are worth every penny. I know you can run o rings etc with the stock filter, but its still junk.
Gutted the muffler & added a Saw Salvage deflector. Today, put on an A1 Design air filter setup . I made a quick test cut, looking forward to spending an afternoon cutting and really testing if. I haven't had this saw a lot. I am hoping it will wake up the way the 620p has!
A2 Designs makes kits for Echo's CS-620P(W) / CS-590 and for CS-501P / CS-4910 chainsaws. The 620/590 fits within the existing air cleaner cover. The 501P / 4910 kit includes a 3D printed spacer to make clearance for the bigger and better filter. Echo CS-590/620 Air Filter Upgrade
I have one of each of those kits on my 620 and 4910. They're a little pricey, but I think they're well done, effective, and make filter cleaning much, much easier.
The A2 kits are not cheap! The flip side is the horrible design of the OEM filters. I did add o-rings, but was always concerned about fines getting into the carburetor.
Ind Ineed they are not, but I don't like the design of the original filters; I much prefer the canister type for increased surface area, better filtration, and easier cleaning. I tend to keep equipment forever, so if I mod something it's usually to gain dependability or durability. I think these filter adapters are worth the money for a saw you intend to keep for a long time.
