Now that’s an honest video. I was about to get the straight shot. I just cut firewood for the house. I’m gonna stick with the stock muffler. Thanks for your honesty!

[@mbflower]

One thing not covered in this vid is fuel mileage. If you're stopping to refuel more often, then you're not saving any time over the course of the workday. Great comparison!

[@PimSchouten]

You are with a 500I. Muffler modded a bit of saving, build, significantly more. I’ve build both.

[@randykeech3557]

i wonder if results would be differant if did a carb reset. maybe just swapping cover and running a few cuts isnt enough time for the m-tronic to do its adjusting and get peak performance from them?

[@istra70]

Just what I want to say. Did chainsaw reset ?

Here's what you do, you keep the original cover for working and you buy the other two mod covers to impress friends and annoy the neighbors within a five mile radius! * Good and honest test video 👍

True story

[@danielmcconnell1096]

I love the video. The stock cover was designed by Germans who are perfectionists when it comes to designing performance out of the box. But ultimately we are goofy Americans who love taking the mufflers off of everything.

[@White000Crow]

Most of my saws are ported, higher compression, and a couple are over bored. I open up the mufflers a little to help them flow better. Some people will throw a bark box on stock saw and expect magic.

[@troopygino]

Very interesting! I was looking at getting one of these but if in a real world scenario its not only slower but loud as hell I think i'll give it a pass haha. Fairplay nice scientific approach here.

[@eurokid83]

I don’t know why anyone would waste their money on these muffler covers. Louder than shit and not a lot of gain. A modded factory muffler is all you need.

[@joescissorhands141]

I don't think it was your methodology I think that was spot-on (like your bars-comparison video, you did more-than most do!!), I also think you misunderstand their claim because I've only seen their "best-of" HP comparison sheet and it doesn't say "in the cut"....I'm not surprised *at all* that an OEM could outperform it in certain conditions (conditions of, say, frozen/larger woods), and that the open-shot coverS are going to rev outta cut (or in small wood) better, but we of course care about in-the-cut, hard-wood cutting not free-revving or 6" logs w/ a 660....IMO the problem is these covers are just negating the performance benefits of a muffler, "throwing the baby out with the bathwater" by effectively negating the muffler by open-hole'ing the thing. I'll make a video once I've tweaked mine but I actually use a front exit similar enough to these, however I have a "baffle plate" of sorts sandwiched in between that forces the exhaust pulse to shoot right back to the exhaust flange (it's a curved plate) so the back-pressure, scavenging, *and* final muffler-escape-portage are all optimized, letting you get more power w/o the noise and w/o the fuel waste (I can only imagine the piss stream of fuel coming from the bottom of one of those boxes' exits, must just puddle down to the crankcase below :P ) They are good exit-plates, for sure, but the muffler needs a baffle, I know OEM-baffles are notoriously over-choked and one of the reasons is EPA but in a no-EPA world there would still be baffles because there's no room for tuning long-pipes so you have work 'in a box' :P

[@vincentlaguardiagambini5702]

Great video, you earned a subscriber. It would be interesting to test these in a chainsaw milling application; long bars and wide/long cuts. I'd imagine torque would be a bigger factor than HP, but the long cut times would be telling. 17% off a 5 or 10 minute cut could be huge. Lower temps could be really beneficial as well.

[@TheDurbinCompound]

Good point! That’s where you save the time! The torque is obviously improved because we couldn’t even get them to out cut the stock cover until we put an 8pin on it.

[@johnlyngdal8601]

Well done. Were the saws run through the autotune sequence between the different muffler configurations. It would be interesting to run the test with both a 8 pin and a 7 pin rim as that might reflect in the results if the torque profile of the engine was changed.

[@justinmcginty9975]

I believe the stock out performs in real world because instead of straight cut you are dogging and loading the saw up more… this means you drop rpm and rely on torque and smaller port with higher velocity always equates to more mid to low end torque. Great video man

[@thetruthisoutthere1661]

I like the idea of getting maximum air flow while running the stock exhaust. Seems like those cool looking add-ons are a moot point while increasing air flow is better for engine longevity.

[@aaronbowles7541]

So what you’re telling me is that the engineers who spend millions of dollars per year on R&D combined with decades of data actually know what they’re doing?? Great video. I love indisputable data!

[@fabzacres-blackcat]

Haha 😆 .... amazing all the peeps that think that are smarter/more clever than the engineers at Stuttgart and Stockholm ! Looks like they’re not

[@rydplrs71]

The only reason engineers get a bad name is in general they are constrained by budgets or regulations. Anyone who has ever designed something for production will happily tell you it could be much better if optimized for performance and or reliability only.

[@davidjanuszewski5020]

Sir, truer words never spoken, the major saw manufactures are good at what they do, competition keeps them on their toes! Now if you want to hand finish parts and tinker with the mechanics of these saws, then you can help them a little, but over all they are what they are.

[@aus71383]

maybe you didn't watch the whole thing indoors, trying to be scientific, stock was slower outdoors, in varying diameters, with bark inclusions, stock was faster.

[@TheDurbinCompound]

Yep! So where it counts (out in the environment cutting wood) it’s faster and quieter. These enhancements help with things like cylinder temp and flow, but ultimately they don’t make you more productive, whatsoever.

[@blkmustang007]

Stock cover won? Almost like the stock cover had millions of $ of engineering behind it or somthing hahahah I think the aftermarket covers need some tuning to really shine since you are changing the exhaust pressures. Great vid.

[@kylestiffler4540]

Did you forget how much you raved about the bark box in your previous test 9 months prior to this. Maybe Makeup your mind,

[@joescissorhands141]

4mo later I come across this again and can only say my conviction in my comments is much stronger, it bothers me because this would basically mean that these "open dump" muffler mods (whether it's via swapping faceplates, or boring a 1" hole into your faceplate yourself-- unless we're gonna see assertions that the deflector is doing some magic which I promise it's not, not beyond 'deflecting' lol which is nice but is all it does) The reality is that these faceplates SHOULD lose to OEM, 2-strokes rely upon expansion chambers for proper performance (exp.chambers, and the addition of silica's to alum., are the 2 biggest factors in boosting racing 2-strokes over the past half-century) So yeah the lawn equipment 2-strokes like chainsaws, w/o any expansion chamber at all, they are - to put it mildly - they're finicky when it comes to their mufflers. These faceplate replacements, while fancy-looking, are effectively operating on the idea that "no muffler is an optimum" and seek to negate it, especially that straight-shot one that has a 1"+ hole literally in-line with the exhaust-pulse from the exhaust-flange (which *should* be assisting in cylinder scavenging for the next ignition) Further there's the watering-down of the next charge, as the cylinder re-uptakes from the muffler during a brief point of its stroke and it *usually* pulls in a mix of burnt exhaust charge, and fresh "spilled" charge, but w/ these faceplates you're mixing atmosphere in and diluting this as well. Results? Should increase trigger/throttle responsiveness and speed to max-RPM when no-load (or light-load) but absolutely destroy power on anything real. Both Jennings' & Blair's books make points to mention that, for muffler escape sizing, that going too-large is very bad and that too-small isn't so worrisome, IE you're far better at 80% of the optimum than at 105%, and the figures for muffler-exit sizing I've seen are on the order of 50-75% of exhaust-flange, which is barely around 1" on 660's (1.2x.75ish exhaust flange if un-ported), so hearing these covers introduce exits of .8" and >1" just further explains why they *shouldn't* work... IF you use a proper baffle 'sandwiched', I mean a whole baffle wall to effectively make 'front & back portions' of the muffler, you could use one and greatly increase power (but still not as much as a flat front wall, the 660/661 mufflers are great in that the charge can come down&sideways and 'bloom'/bounce back at the exhaust flange en route to the primary OEM exit....if/when modifying this muffler, your best bet is simply over-sizing this hole, because it still allows the exhaust pulse to utilize that whole big can, expand, shoot around&back&past the exhaust flange on-way to that upper crank-side OEM hole, because it *has to* if you keep that the only hole, but you can go and double its size and thus alleviate "EPA-imposed choking", you can "have your cake & eat it, too" if you're the type that's using open-dump mufflers, they are genuinely the worst idea I am blown away they're sold (aesthetics? They look great..)

Not hatin on this at all in anyway shape or form BUT hear me out. If thats a 661CM it has the Mtronic and it auto adjusts too stuff...so in other words maybe it acts better for the stock because thats what its used to? I could be 100% wrong but somethin i thought about it.

[@TheDurbinCompound]

I thought that as well. It does hunt around all the time in the cut. So it’s adjusting constantly. I’m not sure how far the limit is for adjustment so with these muffler covers it could need more tune than the m-tronic can give it

Awesome, unbiased, comparison. I dont think it can be done any better, and the numbers dont lye. Myself I've discovered that instead of a dual port or some 3 port mufflers a single large port works much better on the saws I've ported. Kind of like a 3 inch exhaust on a car flows better than dual 2 inch. Less surface area and boundary layer I think. Great video I loved it. Thanks.

[@larrywarner9314]

I disagree with about the bark box I put one on my 440 and my 460 magnum and it made both those saws really work good for stock saws , then I ported them both and I'll tell you wow !!!

Jason is the man! I have a 7900 from him that is amazing!

[@hollywood7927]

I'm sure you know enough to know these are mtronic saws and they automatically compensate for restriction, altitude and temperature through the intake air charge. However, when you make this large of a change to either the intake or exhaust flow, the ecu doesn't have the ability to fully compensate for it. At least, not within a tank of fuels time. I've never been able to get one to fully compensate a large change like that. That is, unless you perform a factory reset. There's a simple reset procedure that takes the "learn" out of the ecu and allows it to make larger compensations in flow. They are fairly forgiving thankfully. I've never been able to max one out. I'd even recommend performing this procedure if all your were doing is cleaning or replacing a heavily soiled air filter. Just to speed the process up. That being sad, I can't promise you that the results you got would change all that drastically. Reason being, is different saws like different muffler designs. A 25% reduction between the overall circumference, or circumferences if you have a twin port design (older design) of the exhaust port window (at the cylinder wall, not at the flange) should put you in the ballpark of what size you need to make your overall muffler exit. Allowing an adequate amount of exhaust charge to remain inside the muffler body and exhaust runner, whilst still allowing that same charge to fully exit on the next stroke is the name of the game. I've found that multiple side exits, for most work saw applications provides both great flow, to rid the built pressure, and enough spent exhaust charge to pulse rearward. This is where you can either help or hurt performance. The manufacturers have a set decibel they have to be below and a set EPA standard exhaust hydrocarbon (ppm) they must be under at idle and whilst in the cut I believe. They design the engine around those standards, not around overall performance standards. So, you have some wiggle room to play with. With a front exit cover, there's too much of a straight shot, where all of your exhaust charge is going to flow straight out, and all you're left with is raw air. You can get away with a front ported cover, but only if there's enough deflection or restriction taking place to slow down that exhaust pulse. They used to make a factory twin ported muffler for the 460's. Look at one of those and you'll see what I mean. Those made a huge difference in the performance of those saws, as it complemented the stock side port, but still didn't "free flow". Back to the 25% reduction. Calculate what size exhaust window you have at the cylinder wall, reduce that size by 25% and that is your total you have to play with, no matter how many ports you want. You can drill holes in the muffler if you wanted, as long as the sum of those holes is no greater than 75% of the total exhaust window size. That's a good number to stick with on a stock saw. If you start playing with blow-down duration and port timing, you can play around a little with that number, but not on a otherwise stock top end. If you want to take it a step further, to complement that shiny exhaust cover, take about .5mm off the trailing side of your flywheel key (only the portion that is visible as it's sitting in the crank). If you grind the entire side of the key down, it allows it to rock ever so slightly, and it will shear eventually. After you take your material off the flywheel key rotate it counterclockwise to take up the slack while you have a piston stop in the head, and torque her down. Make sure you have a clean flywheel, and a clean crank. You want it to seize in place and not move once it's in place. If it moves, it will shear. After all is said and done, reset your ecu, and enjoy! To answer the question some of you are asking, yes the timing is controlled via the ecu. However, when you move the flywheel, you move what it believes is top dead center, so you move the entire timing curve. Don't overdue it. The flywheel should not move more than about the distance of half of the gap of the cooling fins. Assuming you don't have a degree wheel on hand. That's about 8-10 degrees, which is more than you'll want to go if you're using low grade fuel. In fact, if you're not running at least 91 octane, don't adjust the timing. It'll cause sporadic pre-ignition, especially when it's hot during a long cut and you'll cause issues you don't want to deal with, besides just loss of power. Cheers and happy cutting! I wouldn't recommend any type of modifications on any saw used for wood cutting! These recommendations are for test saws or race applications only.

[@danielsmith8659]

Great video. I actually just bought an Egan straight shot.

[@DrgnRebrn]

I know this was 2 years ago. I think it's valid to point out that the after market mufflers most likely each require a custom tuning to balance out the change in exhaust flow. IMO, this test only showed the advantage a tuned muffler/engine combo can make. If you redid this, tuning for each muffler before you run, then I believe you'll find more value in the results as they'll each be running as intended.

[@Mr_Clean]

661 is MTronic. Adjusts automatically.

[@TheDurbinCompound]

[@jamesdepalma6341]

I'm not so sure about that, from all I have read M-Tronic V3.0 still requires the reset when making a larger change such as porting, open pipes, covers, etc. You could be right and I could be wrong. It would be nice if you did this video again with resets recorded before each pipe cover used. Also try it with the air cleaner spit back baffle in and out. This would shut us all up on the topic once and for all LOL!!

[@TristanH7290]

@@jamesdepalma6341You’re absolutely right about the porting part, but the M-tronic system doesn’t require a recalibration for muffler and air filter modifications. The only time a saw should need a recalibration is if there is a substantial and sudden change in temperature or elevation.

Why do most (all that I have seen) muffler mod covers send the hot exhaust back onto the bar or straight back into your face when milling? When milling with an Alaskan mill with either of the two you show the exhaust hits the log and comes right back into your face. It also heats the mill and makes it hard to hold onto. Why can't they make one that addresses this issue? Send the hot exhaust "UP"!

The saw now has pull so you can yard on the handle and it just says okay let's keep cutting no bog. To get real gains the whole saw needs to be attacked a simple bolt on is just a gyimic in my opinion too.

[@davidberrier5894]

Did you tune the carburetor

[@kipmyers5897]

I enjoyed your video ....I found on my 660and my 066 that with a 20 inch bar I go to a bigger sprocket that's where I gained a ton of speed I also know my own muffler mod I use alot more fuel bc I turn my screws out almost a turn my saw runs cooler.....the bark box I don't see how a bark box has much back pressure I mod mine down low so that the exhaust bounces back for pressure but hey I'm a old go-kart racer I have a 2100 with a tuned pipe and that's a forty percent HP gain but who can use a saw with a big pipe .....long pipes resonate sound waves .....I suggest you thro tinmans homemade short pipe in this race....I love the look of a bark box but tme it's bling I get better results with a drill bit and a little 20 inch bar you need a bigger sprocket on a big saw .....my 60 cc 311 junk with two holes in the muffler is faster than my 660 up to a 20 inch log and I run a 24 bar on 311 ,,,,,on that size log I'd put my 460 and my 461 against the bigger saws .....the big saws use tourque and 70cc is the fast cutters up to a certain log then a big saw walks away on a big log .....your cutting a small log with a big saw and a small bar and I bet a 7 pin .......but what do I know I own 30 classic husky and sthil and my 3120 is no speed demon but a torque monster ......but hey us saw guys can we agree great hobby we love them we love to debate ......what if I said I HV a homemade saw that puts out 19 HP on Dyno and can cut all day would you call me a liar? I thought about marketing them .....won't tell you the secret but no sthil no husky and it lives in real world cutting .....I'll make a video of it if I think it will get views

Gordie/West Coast Saws for the win

[@ralphsoto3223]

Race them all at once think your arms got tired from cutting cookies lol

[@xwayesknbent]

I did my research and I ead that having a dual port is good for your saw. not heating up as much, less fuel consumption, more torque and longevity of the saw. now are these actually measurable test results. or are they not. not sure. I used a stihl 461 with a dual port, then I got a 500i with stock muffler cover. the 500i cut 3 to 1 blocks of firewood over the 461. the fir was pretty uniform as well not a spire point. so I got the 500 ported and I found it ran better. I git a second 500i and put a bark box on it. I notice its loud but performance not all different than just a dual ported muffler. is there a test like this you could do. instead of just time in the cut. maybe also which is better for 32" and larger snd 24" and under classic as well. something like that anyhow

Egan also makes muffler covers for a wider variety.

[@beezletrip6]

I've always told my buddies that bark boxes don't do Sh%t

[@TheDurbinCompound]

Exactly! They don’t make you faster

[@davidash7536]

I just put on the Egan one on my 661, love it.

[@Hambonebodi]

😂 i love the concrete block as a weight ❤, mufflers are designed to deliver the power and torque over a wide range .

[@michelefoianini2054]

It's like a bigger turbo on a Supra, isn't productive but... God damn I love it...😂

[@hunterhess9222]

Hey man where did ya get the black handle cover side support? Thanks

[@Agent40oz]

Literally just borrowing my buddies ms461 with a wcs and just searched to see how different stock versus the bark box sound and wound up on this great informational video 😂👍

[@reallife2849]

My old ms360 , 20 inch bar , oiler turned all the way up since new and every tank of gas is 3/4 tank of oil used . It cuts 30 inch maple rounds in seconds. Once the ring’s seated it became a beast vrs weight for hours of cutting. I cut a lot of wood on a new chain before it’s first grind.

[@SixOFord]

Egan ran the coolest. Interesting. Heat is the devil.

[@etthealiengamer]

I got a ms 362c with a bark box and it really woke it up it can stay with a ms 400c with a bark box and I put the stock back on and it can't keep up with 400 so I believe that the bark box is worth it

[@duck-n-cover477]

My experience after two years (Bark Box in my case)... I used it on a 400, great saw but fades a little in the heaviest work. When burrying a 20" bar in a big stump or bucking over 20" D logs, the stock cover sucks and the muffler helps it snort its way through. I think the torque benefit matters more here than the HP or speed. I went back and forth between stock and the muffler mod, and finally settled on the muffler mod. That little bit really does help extend the saws capability. It matters in the do-it-all size saws, like 60 to 80cc. 50cc saws are much more limited by displacement and 90cc saws will bust through almost anything. Under most other situations, like bucking less 18" D logs or limbing, the muffler difference isn't as noticeable, except it sounds awesome and (with hearing protection) it makes using the saw for work, more enjoyable. Did I say "work is enjoyable"? Yeah, these mufflers are fun too.

[@Husqvarna575XP]

So. I'm a fulltime logger - What do you recommend for the muffler? Just put an extra port on the stock muffler? Or do nothing? Did you test if the MaxFlow filter make any difference? Greetings

[@lesjocelyn4491]

Why don't you wear protective eye wear?

[@TheDurbinCompound]

Oh I was wearing my safety squints! Most effective!

[@black_sheep_fab9411]

I see a lot of this on car stuff. Guys cut the muffler off or get a louder exhaust and thing it picked up 50 hp when in reality it's just louder. I have been looking at these for quite a while and wondered how much gain there really is vs just people having a louder saw thinking it's more powerful. Just like all the guys modding mufflers with no real world data. And I mean realistically if it's 4 or 5 second a cut faster on a 36 inch log your never gonna know. If you stop the chain a time or two or pinch the saw ur gonna lose it all and then some. Its more of a novelty to me. Maybe on a max effort ported over the top deal but not a stock saw doing stock saw stuff

[@thomasgronek6469]

thanks for the video. If we think for one minute that the major manufacturers didn't use multiple designs to optimize the saw's performance then we are mistaken. In the search to grab every part of a horse power the competition is harsh, and we must consider back pressure as one of the primary drivers of the design... No, unless it's a tuned pipe, I think that the manufacturers will do better than and after market producer.

[@matthiasmacandrew1267]

Was the M-Tronic reset between the various exhaust change overs? I definitely experienced an increase in power on my 462 and 500 Stihls with the WCS bark boxes. Also was the spark screen removed from the stock exhaust? Thanks

[@EricChmelarsky]

Where i find a opened up muffler helpful, spooling up, or the crack, getting up to full RPM quickly. Limbing is much easier when the saw doesn't lag or hesitate getting to full RPM. If I should gain some power in the cut, i consider that a bonus.

[@davidfenton3910]

Started off promising but finished feeling somewhat disappointed. The weighted set up and compare between the 2 custom mufflers looked good and inspired trust but the change of conditions with far less control of variables (no weight, different log) makes comparisons useless. Basically if you're going to do something and put in in a comparison video ... please keep the consistency and control of variables there so more useful information is provided. Fix up the above and I would consider you to be passing 12-13 yr old level science experimental design. If video was limited to comparison between the 2 after market mufflers and that data then, it I would consider it to satisfy basic real world comparison for useful knowledge. Thank you for the video and the useful comparison between the after markets, that info was good. sincerely david
