Chainsaw Muffler Mod Westcoast Saw muffler Stihl MS 261 C-M

[@foggyvalleyacres]

Check out this video for my thoughts on the muffler mod and the first cuts after installing the muffler mods kzbin.info/www/bejne/sKPUYoKdnptsoNU

[@mikehampton848]

Just drill 3 3/16 holes in the front, take a few baffels out of the intake, retune and poof. The only thing you will miss out on is the sticker from west coast saws. 💪😁

[@foggyvalleyacres]

I debated that or cutting slats with a grinder, I thought this was a cleaner look so I went this route. Definitely cheaper ways to get the same results but I liked the cleaner look.

[@thomasolsheski4857]

The drill bit for the rivets is 17/64 according to Gordy.

[@foggyvalleyacres]

Ok, where did you find that at? I couldn’t find anything on the website and no instructions so I shot from the hip and drilled holes in wood til it fit lol

Thanks for this. Excellent vid. It helped me.

[@foggyvalleyacres]

Thanks! I’m glad it helped! How are you liking the mod?

[@Living-The-Dream]

Great video !! I’m still on the fence for this mod for my MS 261c. Would be nice if it could be done like I have done for my MS 362C and the MS 500i. Both of those were simple and worked out real well. Appreciate your efforts making this video 👍👏🇺🇸 Rick

[@foggyvalleyacres]

It was definitely worth the time, it didn’t take long really and was relatively easy to do. Did you do a muffler mod or aftermarket muffler plate on your 362/500i?

[@Living-The-Dream]

@@foggyvalleyacres Morning, Yes, I did the west coast bark boxes on both the MS 362c and the MS 500i. I bought the MS 261c back in September but haven’t done anything to it yet.

[@superflanker972]

I've done drilling holes on my stihl ms381 exhaust and it runs very great also it prevent the top cover to melt😁

[@foggyvalleyacres]

As long as it gets some extra flow out it doesn’t have to be fancy to make more power.

[@jimsworthow531]

nice touch with the nut-serts.

[@foggyvalleyacres]

yeah, they worked really well, better than I expected to be honest.

[@dennistewell6638]

nice mod, sounds great, I had to retune my saw a bit after my mod

[@foggyvalleyacres]

Yeah, I’m happy with it. Not a whole lot louder which I was hoping it wouldn’t be obnoxiously loud. This one is m-tronic so it is supposed to self adjust.

[@danspencer4181]

Nice clean job man! Just ordered the same port for my MS261C. Any notice in power increase? Hoping it gives it a nice deep sound but not too loud.

[@foggyvalleyacres]

Check out my latest video, you can hear it actually cutting in wood. kzbin.info/www/bejne/sKPUYoKdnptsoNU Might be slightly more power but it revs out a lot faster and stays reved out a lot more in the cut which definitely cuts a bit faster. Power wise it’s honestly hard to tell a difference. You’ll be pleased with the sound, it’s deeper and slightly louder but not obnoxious which I was honestly afraid of it being too loud also but it wasn’t.

[@danspencer4181]

@@foggyvalleyacres thanks so much for the response man! I will definitely check out this video 👍🏼👍🏼 Excited for mine now lol

[@foggyvalleyacres]

@@danspencer4181 you’ll be happy with it, just take your time and it will turn out great!

[@K-Rivs]

I see you have the light04 bar on there. Do you know the part # for that off hand? Looking for the light04 for my 261. Saw sounds great!

[@foggyvalleyacres]

I’m not sure of the part number, I got it on eBay. I’ll look to see if I still have the box for the part number. If I were to do it again I would get a sugihara bar, definitely better quality after having one on my 462.

[@Fly4aWhiteGuy]

Are the caps over the bolts necessary? Can I just leave them out?

[@foggyvalleyacres]

They aren’t necessary, they are just dirt/dust covers. I keep them on to keep debris out that might get packed in the bolt heads.

[@curtis3653]

Good enough for the girls I go with

[@foggyvalleyacres]

Haha! I like it!

[@dardy355]

nice work mate

[@foggyvalleyacres]

Thanks!

[@barnyardbrio7597]

sweet video bro.

[@foggyvalleyacres]

Thanks, hope it helped!

[@barnyardbrio7597]

👍

[@foggyvalleyacres]

Thanks!

[@dennisingram6748]

Would removing the front two plugs not allow for free-er flowing exhaust without voiding the warranty?

[@foggyvalleyacres]

Those are just plugs to keep dirt out of the screws that keep the muffler screwed to the cylinder. That would have been nice if that were the case though for sure!

[@timkelley6616]

That saw only has a 90 day warranty anyway being it’s a professional model

[@foggyvalleyacres]

@@timkelley6616 I wasn’t all that concerned with the warranty, I would do it to a new saw and not be all that worried about it.

[@67L48]

@@timkelley6616 Incorrect. Warranty on a MS 261 is one year. It doubles to 2 years when you buy Stihl hp oil. This is the same program across all the tools: blowers, trimmers, pole pruners, etc.

[@RenaissanceThinking]

​​@@timkelley6616mine has a 2 year warranty. Just bought it last friday at the local dealer.

[@glennminix6900]

Got a question is there a bark box for Ms 271 farm boss where to get it

[@foggyvalleyacres]

No, 271 is a single piece muffler. That’s the reason I did this muffler mod to my 261. Very easy and cheap with great results.

[@foggyvalleyacres]

Thanks!

[@majorahole]

Any link to the part?

[@foggyvalleyacres]

Different size ports for different saws so make sure you measure first…. westcoastsaw.com/collections/all-products/products/universal-exhaust-power-port?variant=43412269072614

[@lupastuff]

Why not get the WCS Barkbox ?

[@foggyvalleyacres]

They don’t make a bark box for the 261, it’s a single piece muffler, bark box is for a 2 piece muffler.

[@delanuez]

what size did you order?

[@foggyvalleyacres]

It is on the drop down menu on their website specifically for the 261. It’s an odd size can (smaller) than the 2 piece mufflers make sure you get the one for the 261.

[@gwp1ohio]

this only increases the outflow, you didn't really do anything to the inside to create hp gains....?

[@foggyvalleyacres]

No real go gain, maybe very marginal but it breaths much better. Breathing better results in much faster revs and holds rpm much easier when cutting.

[@johnsb1550]

Maybe I missed it but why are you doing this? Warranty is obviously void now

[@foggyvalleyacres]

The saw revs out faster and is able to keep revs up when cutting. Yes warranty is voided but I wasn’t too concerned. Normally warranty work takes forever and unless it was major damage it is easier to fix it than take in to a shop and wait a month for them to fix.

[@johnsb1550]

@@foggyvalleyacres that's fine, just wasn't sure why

[@foggyvalleyacres]

@@johnsb1550 it makes a noticeable difference, it stays in the sweet spot of the power better after the mod.

[@loggerjake8506]

Could you just use normal pop rivets?

[@foggyvalleyacres]

If you had one big enough, I had a bend in it for it to fit better and I think the bolt would hold it a little tighter.

[@eurokid83]

I used 316 stainless pop rivets with backing washers on mine. They were a bastard to install though. Thought I was gonna break my rivet gun.

[@foggyvalleyacres]

@@eurokid83 I didn’t think I would be able to get a tight fit before the river would snap off unless my bend was perfectly lined up with the contour of the muffler. What size rivet did you end up using.

[@sac2808]

JUST GET A EPS EXHAUST.

[@foggyvalleyacres]

They weren’t out yet when I did this. A little too loud for my liking as well.

[@christophercolt1361]

REMEMBER! Whatever ya change at the EXHAUST will have to be reconciled at the INTAKE! Small engines do not have the BACKPRESSURE like LARGE 4 CYCLE engines and therefore a drastic EXHAUST change can & will fry the motor!!!!!!!!!!!!!!!!!!

[@foggyvalleyacres]

Thanks for the comment, useful info.

[@brettbrettson69]

2 strokes work on sound waves not back pressure

[@cgriebel1]

Hopefully you're not building engines...small or large.

[@NASCAR_NEAL]

I agree with this. Leave them alone if you don’t care about longevity. If you want a loud cool looking saw that claps like a diesel engine Jake brake, then spend ya $ on it lol
