Donny walkers chainsaws showing different muffler mods

[@michaels3288]

love my 261. My 025 cut wood well too here in Pa. I think the 025 was underrated.

[@donnywalker4691]

Both great saws

[@MrHuntermikey]

Really like how you set up the 565-572 mufflers Donny. Everything made today is strangled with smog or EPA limits ect

[@Matt-416]

I don't really know if that's completely accurate. While almost all current saws are strato, I don't see Echo nor Stihl running fully baffled mufflers, aside from their older designs. Those Swedes must have an EPA-type of organization that makes California look like Carolina. I loath those one piece tin-alloy mufflers that Husqvarna is using.

[@donnywalker4691]

Those canucks eh bud

[@wednesdar452]

The 261 with an 8 tooth sprocket is a heck of a ripper for limbing up trees/dealing with brush.

[@Broderick362]

Great video Donnie!! I like to see that 550xp all put together with wrap handle and dogs!! Keep up the good work!!

[@rodmctaggart4520]

Good stuff Donny. Keep it coming. Chevy get's my vote.

[@paulrhodes482]

Great video buddy! Back at the doctor for me today. Rough last night lots of nerve pain not much sleep. Have a great night my brother.

[@stihlhunter]

And ice in the glass. Shop Website in the description...Every one... Just rooting for you

[@robertenglaish4093]

I own a 550 and a 261 use them both good saws 🤙🏼 thanks for the muffler ideas

[@jefflohr5533]

Need to send a saw to this guy. He seems to really know his stuff. I saw a dial indicator and degree wheel hooked to this engine and now I watch it scream and hit a high note so crispy n clean! He is good! I might send him my 462

[@thebradleysoncatbirdhill6849]

Great discussion, Donny! I always look forward to your videos, and I've learned a lot already! 👍 By the way,...Dodge man here!

[@donnywalker4691]

I have a dodge cheers

[@travisgilbert8416]

My Dodge 12v Cummins has been a great truck even if she does need paint and a new interior... just keeps on logging the miles!

[@backyardfirewood9852]

Great video Donny! Saw you on BB Ray’s channel. Ford for me too and the my 550xp Mk2! I saw the walkerized 620p! I really like my 620p (stock) want to put on a modded muffler though...

[@tc3603]

That 881 sure is a big fella

[@Morpheen999]

I'd love one of those 261 2 pipe mufflers!!

[@justinweaver8787]

Great tips sir thank u.

[@putfilesnfriend1]

what an awesome video. thanks so much man

[@Matt-416]

That 550xp is hit or miss. Mine is a complete basket case. Three months at the nearest dealer [68 miles away ( three years ago there was 3 in town and at least a dozen within 50 miles)], and they reset, updated, and calibrated the Auto-tune... It still hates to idle warm or cold. After 5 or ten seconds it conks out. Then starts like it's flooded to the gills, blowing smoke and sputtering up high. I'm definitely not alone in this particular experience. Having owned both the 550xp and the 261c, I have to agree with you. The 550 feels better. It seems more nimble. I just wish husky didn't make their bottoms round, as it hates to stay upright even on the flattest of surfaces. Rollie-pollie. I will definitely acknowledge that the MS261c has more power, but pays for it with an almost bloated feel. That, and I find the M-Tronic to be superior to the Auto-tune. Having worked in this area for 25 years, once husky pulled their dealers out and Stihl completely took over, I know of ONE M-Tronic that's fouled up from a bad solenoid. And that's multiple companies running at least a half dozen saws. Everyone I know of that's still running fleets of huskies has had at least one saw go completely wonky, from the 550, 562, & 572. With the complete disregard of essentially the entire east coast, I just don't see them being successful long-term.

[@donnywalker4691]

Was your 550 the new mark 2 but I totally get what your saying

[@Matt-416]

@@donnywalker4691 I believe so. It's definitely a mk2. Manufactured in '19, bought it in early '20.

[@Matt-416]

Don't get me wrong, I absolutely love that little saw, but it's moody.

[@nateolmsted899]

Awesome like always

[@darrelljohnson4658]

Thanks 😊 sawrus

[@plowmaster1206]

Pretty impressive taking muffs down with a torch lets see a vid. Merry christmas donny

[@ronsilva516]

A good comparison on the muffler 👍

[@travistelford1827]

Do you ship and sell the modded mufflers for the 572? I'd be interested, as I've seen some major hack jobs on those mufflers and yours look nice.

[@JoseOchoa-wp8yr]

This….

[@troymcleod7008]

So the 572 with .6 of a hp gain really not worth the effort mite be if your porting the saw maybe 🤔

[@dynojoemods2764]

Very Nice!

[@Pack_the_Ripper]

This is so freaking impressive!!!

[@stihlhuskyworkin1011]

Great video donny 👍🏼 what kind of extra power do you think a 346xp would make adding a dual port muffler? Thanks for the cool content donny. Keep it up 👍🏼

[@donnywalker4691]

Definitely big gain on the 346 one of my favourite saws

[@stihlhuskyworkin1011]

@@donnywalker4691 ok. I didnt know if it would be worth porting the muffler on it or not. I’ll definitely be doing that now lol. Thanks donny 👍🏼

[@jensenwilliam5434]

Hello Donny!!

[@harmonicliving3507]

Nice muffler mods!

[@codybrown3946]

Awesome Donny thank you

[@darthtrump4428]

@Donny Walker i've heard that general rule is the muffler exhaust port should be 80% the surface of the cylinder exhaust port is that correct?

[@garyjones7219]

Hello from Northern Ca. Does modifying a muffler help keep the engine cooler? Thank you for your videos.

[@JoseOchoa-wp8yr]

Do you sell ported 572 mufflers

[@elieregnier7783]

Awesome donny👍 do you have a part number for that 288 muffler deflector?

[@mrfirewood6215]

Donny, can you let Gordy borrow a 550xp mk2 to build a set of better dogs for them?

[@rottiejakeluke]

Hello Donny, Have you seen the H L Supply dual port/tube muffler cover for the MS500i? Is so, have you any information on that vs.WCS or Egan’s Bark Box? Thank you.

[@nurdinnurdin8542]

Super

[@mattlee6367]

Hi Donny iv been following your vids for a long time now and love watching them as have learnt heaps. Was wondering if there was anychance u cud do a video on how to re calibrate m tronic saws. The reason I ask as theres not really much info out there on how to do it for different saws I.e Stihl 362 661 etc then the different versions of each can be different to do. Just an idea I thort I’d put to u seen your the man to talk to bout saws. Cheers Matt

[@nrthrnstncrft2420]

Is it worth doing the two sided muffler port on the 372 and 390 Huskys if the cylinder is stock?

[@donnywalker4691]

Yes for sure

[@jonathanwebber7532]

I have a Stihl 362 with the one piece muffler Should I do it like the 260? Or replace the muffler with a 2 piece and get a bark box?

[@donnywalker4691]

Do it like I did with the 261

[@jonathanwebber7532]

@@donnywalker4691 thanks for the reply Looks like about 3/4 inch I.D. Stick with the same size for the 362

[@shawncordeiroTerraceBC]

your on jingle pot rite ? I orderd a 562 from you and you did the walkerized mods with duals and mailed it to terrace back in fall of 2012 saw sounds great runs great ct to re-start after its been running breafly

[@donnywalker4691]

We moved from jingle pot give me a call about 562 call walkers saw shop ask for me

[@oscarmdog5275]

Hello Donny! On the Stihl 044 and 064, do you like to leave the guts in the mufflers? Do you drill them at all, or just run dual ports and leave the guts alone? Thanks!

[@marcduclos9789]

Really you got to skate wear the pucks going not wear it is.

[@Matt-416]

Play the body not the puck.

[@valentindragulin7753]

How to get some for my 572?cheers

What kind of muffler mod to home saw rancher 450? Always need more power.

[@codysmith605]

good stuff thanks donny

[@warrena8542]

I have a 372x-torq and I want to put dual 288 caps on as you have done. Do you cap the factory hole on the top or leave it open as well? Thanks from the Kootenays

[@joelbeans3802]

Hi Donny, do you do muffler mods on every saw you port or on request? Thank you!

[@donnywalker4691]

I do almost all but some people want it different ways

[@werweiss7561]

Great video as always! Keep on gooing like that. I just bought myself a 372 and of course there will be a muffler mod. Is there a website where i can get those caps? And is the muffler completely empty? Greetings from Germany...

[@MrMok70]

Awesome and informative video, Thank u man

[@WarningHumanity]

How can I order one?

[@thebcrew8942]

Does Walker’s ship saws to the lower 48?

[@jjm4794]

How can one get one of those mufflers for a 562 ? Thanks

[@ravenshield7823]

Are you available for a 562 muffler mod?

[@ryanmoy625]

Donny, do you recommend using the muffler gasket when installing a bark box?

[@donnywalker4691]

No I don’t no reason for it

[@fredericdarsigny4397]

Donny is a modified muffler a lot louder than a stock one? Do that mod affects engine's reliability and durabily?

[@dentondunn4346]

A little louder, gives it power gain and gives the saw more life due to getting the heat out of the saw. Actually better for it cause it removes the heat from the saw

[@jonfyfazan]

Sorry to say doesn’t matter what common sense you bring to table about spark arrester screens, because of the increase of large wildfires in California, it’s what can happen to you in court if you are caught without a spark arrester in burn area weather you started a fire or not. Read “Scorched Worth”, millions of dollars of law suits and a kid cutting fire wood caught up in the middle of financial wars between Red Emerson, owner of Sierra Pacific, US. Forest Service, private land owners, Cal Fire etc etc.
