Wow, what a great test! Numbers don’t lie. Very well executed sir!

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!

Honestly if it was to be scientific we would have to remove the human altogether and he could have used a stopwatch shown on the screen. 😎✌️Still fun tho.

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.

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!!

@@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.

I caught a lot of grief over this same test and got the same results, love the video keep it up

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 😂👍

I appreciate this video good stuff I've been interested in both and a lot of great points one thing they have in common is quality

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

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.

Best fair test I’ve ever seen!

new subscriber...such an honest review and very interesting points made...

Thanks for the video from Davenport Iowa

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.

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.

imo, you did a very fair test. enjoyed the video...thumbs up !!

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.

Very nice unbiased comparison!..

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.

I run double ear pro on a 290. Thanks for getting the noise info out.

Good effort man😉👍 Cool that you recorded piston and muffler temps, the Egan really makes a world of difference in getting rid of the heat👍 Just curious if you sharpened the chain on the 28” after the stock cut? Thanks

Not about bling lol it's about getting as much heat out the engine as possible wich will help your saw not overheat. I do Alaskan milling so my saws get hot wich can kill a saw.

Good honest review. Thanks.

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.

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.

Double hearing protection absolutely necessary - special moulded fitted ear plugs and grad 5 muffs. I have a Stihl MS 460 with a bark box and running square ground chain, the combination is very very impressive. its a light sabre ... not so fast on the 660, but helpful. You just don't have to work so hard, but when you have to cut wood the chips are long and it throws them a way. For me its made a big difference, especially on a hot day.

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

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.

Thanks for your honest opinion. Great video

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

My only issue with Jason's is its only 10 bucks less than the bark box I got and the bark box does shoot the exhaust a bit vertical and away from my sweet ubreadable blackened serial number.

Any muffler with an increased outlet on these newer saws with small outlets will seriously drop exhaust temps and save top end life

It's not just the faster cut but the added torgue and power that especially in hardwood makes a huge difference and less bogging down, saw all round performs better with the ESS and air filter in Australian hardwood and large dead wood.

Great vid👍

Now that the stock cuts fastest according to this test I just want the loudest can we do a DB TEST

Great analysis. What I see from this is, If you really want to improve performance for productivity, definitely just skip a simpler muffler mod and just go straight a full-on woods port from a reputable saw builder.

even if you dont gain any speed in the cut. a big thing mufflers help with is throttle response and temps. your saw will last longer since its cooler. your right though for a guy who cuts firewood on the weekends its not really worth it but i cut big stumps at work all the time after we take a a tree and it helps id say. it really woke up the 500i for sure. my boss hasnt gotten one for are 661. made a big difference on the 461 too. i wanna try one for the 400c we just got too and see what that does i really like that saw its light and still pulls good.

I think it’s a pretty fair test mate,I think the different mufflers would probably better suited if maybe it was ported etc,but to run it every day I don’t think so.this is why they have saws with more power .

Thanks for saving me at least 80 bucks lol Great video!

Had a mechanic once tell me that the truck he let me drive wasn’t “faster” I could just hear the exhaust lol been thinking about a bark box for an 036 pro but maybe a muffler mod might do better in real world while not being ear splitting. Would definitely love another comparison to a muffler mod vs these covers on times and noise

Did you jet/ tune to each muffler! If it’s jetted for stock of course it will run better!

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.

Doesn't the chain type and the grind determine the speed of the cut, not the muffler?

Just what I want to say. Did chainsaw reset ?

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

I need one of those to cover the bridge on my electric bass guitar.

Your tests on the straight shot and bark box is right on wirh dyno Joe as far as dyno! Straight shot for the win!

If you also port your saw the bigger muffler is even better. More airflow in more out equals more power and faster

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

How much time was ran after the covers were changed for the mtronic set up to adjust?

Nice video.

My 661 has an autotune function. You needed to recalibrate the saw for each cover for accurate results.

I love how the egan straight shot sounds & performs. I love how the wcs bark box looks but don't like the sound as much. I would like someone to make a gnarly header for it and somehow make it sound cammed to get a hot rod sound. Then i dont care if it cuts or not lol

More throttle response doesn’t necessarily mean faster cutting. Take a dirt bike for example with baffles in vs out. Top end is faster with baffles in but more torque or throttle response with less back pressure and baffles out. Thinking similar here. Designed to run a certain rpm optimal with the back pressure that’s stock. Great comparison

2 strokes need a certain amount of back pressure to run properly. They also need a certain amount of inlet resistance. Mess with either to much, and kaboom.

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"!

Good info

I agree with doing this again and checking temps. Also the Egan sounded like it was revving higher because it was lean and eventually burn of the saw!!! No Four Stroking Sound to it at all. Run again, Check Temps and set RPM's the same. Four Stroking will save your saws.

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