Chainsaw Muffler shoot out, Bolt on performance

Chainsaws adapt very well to muffler mods if done right , here are three mufflers tested

[@jrobi47]

2 stroke muffler design is part science and part black magic

[@ecstans07]

It’s a good idea to keep the heat shield on there. Not necessarily because of the heat coming off the muffler but because it helps keep the cooling air flowing over the fins on the cylinder properly.

[@pureblood324]

I love watching professionals run their saw you learn so much about proper technique and safety he does the same thing every time all the time smooth and direct inefficient. So thanks today's black and Bill two lessons for every video that you do when you're on the saw.

[@donsmith3314]

Thank you! That answered 1 of a couple of million questions i've had about why folks change their saws! I've seen your variety of mufflers, but always thought it was associated with porting them, rather than just an improvement right away with only a muffler! Once again, thank you good sir! Love to all from Northern Alberta!

[@antoniomorgado5304]

Oh yeah! Crazy performance mufflers!Since i did my berclaw style stainless steel muffler for my 372 oh dear lord the saw became a monster!!!!!!!

[@blainstenberg2806]

The interesting thing with 2 stroke dirt bikes and pipes and muffler is the amount of charge in where the power is. Lower mid range or top end rev just by changing the shape and length and even the thickness of the tubing can change the power but the length of the header portion (first out of the cylinder ) makes big difference in the low end torque

[@HYDETREEWORKS]

As a motorcycle mechanic it's nice seeing other people understanding it. The pipe really Is a musical instrument that operates off sound waves. When you mentioned thickness you are changing sound.

[@HQHQHQHQHQHQHQHQHQHQHQHQHQHQHQ]

Now I'm gonna make one myself for my saw! And that 2nd one made from round pipe with wrenches welded to it looks amazing! Wow!

New to your channel... a refreshing change of pace, love your accent, love your trucks, love your chainsaws, love your love of life. Some would say your mufflers don't work (need to use an expansion chamber) but your experience tells me you would be right and the ney sayers would be wrong. Besides, these are working saws and there is no room for an expansion chamber without giving up the versatility of the saw. I love your saw rack and I love thst you stick to the basics when sawing!

[@bryanmayes9234]

Any time you have to add fuel it's cuz U getting more air, the more fuel ya burning the more powah baybay

[@patthesoundguy]

Something else interesting is when you enter the information into an online pipe building calculator it asks for the size and length of the ports and takes that into account. That may be why a particular pipe design works differently than another on a ported saw or non ported saw.

[@sgg8970]

Love your videos but really love your messages and what you stand for Sir! Really enjoyable and I love learning all I can! You have great knowledge and your methods and opinions are truly perfect! Thank you for putting these out.

[@flmulcahy]

I note the old Pioneer 620 in the corner, great old things they were. I still have one, my first saw.

[@joshuajohnson4396]

Hellos. You're a good teacher Buckin who are so enthusiastic about your trade. Thank you Buddy

[@scottirwin1693]

If you want a noticable difference put a velocity stack on the carb. Paired with the pipe, that saw would pull chain no matter what grind you put on it. Love the content BUCKIN. Keep on keepin on.

[@drummer0864]

One of the best comparison vids yet. Iron Horse's muff. really flows. I don't think the exhaust has to slow down to change direction. It just swirls around and out. It would be nice to see if it had vanes, like screw threads to direct it so the flow would just follow the path right out. Happy 4th to the BBR, Army.

[@tazman-kennyfuller]

Great representation of the quik change on and the design of these mufflers Buckin. Takes a bit of time to make them but it is absolutely worth it for the power and throttle response. Thank you. Love ya brother. 🌲❤️🌲👊🪓

hey! Tazzy! I made some myself too

[@tazman-kennyfuller]

[@terrycalvert7812]

I have stihl and husky saws I like both but what I hate about the husky’s is how when you put a muffler on them they got that high pitch girly cry and the stihl has that deep roar but there both good

[@barryhoneycutt3894]

Bucking Billie ray Smith, dam man! I love you, your a great inspiration to a younger generation. I am 70yrs old in Aug 19-2022. I learn a lot, about tree cutting, but even more than that, about life.. Be kind one to another, and enjoy life, for it is a gift. I would like to meet you some day and Morgan, and a few others... Keep doing what you do Brother... god is in it, and it is a mission from Yah/god.. i am looking forward to the 800 mile trip. Prayers and love from SE Texas Bear

[@matthewotis3594]

I used to cut with an old 372 xp and it was a wicked saw. a true handful for me.

[@brucewayne2984]

Buckin, I grilled a steak and fixings and turned you on to watch with dinner. My wife has never seen your channel even though I've been subscribed since your infancy. The only thing that my wife said about this video was, "He's got neat hair"! I thought that was funny! Keep up the good work bro!

[@patthesoundguy]

The length of the header has a lot to do with where the pipe hits its torque. Back in my scooter tuning days I noticed that a longer header would come on later in RPM and a shorter one would be earlier.

[@Im_Old_Gregg]

What you need is a tuned pipe like a miniature version of one on a 2 stroke dirtbike.

[@stevenlaxton3618]

I grew up loving hotrods and drag racing..so the pops and cracks from that "key to the bush" pipe just strike a chord with me..sounds pretty damn rowdy and looks so cool with the scrench outlets..thank for more wicked content Buckin and I see you just dropped a truck packing video so I'll see you there too...have a great day yall and happy Canada day

Great mufflers. A 1. Really makes a difference.

[@HQHQHQHQHQHQHQHQHQHQHQHQHQHQHQ]

Earlier i wrote that i'll make a muffler muself, and i did, today! And i feel the difference, it pulls better and throttle response is also better! And i probably will wear hearing protection now! lol It's a small saw, Hecht 945, 45cc 2.2kW, but difference is there! Thank You Billy Ray for showing these mufflers! I'm excited! =) wow!

[@terrywhite9017]

Good morning Buckin, enjoyed this video. 😊. Love to all.

[@dan-dan-da-treeman]

Thanks for being kind people.🙂

[@phillipparker8947]

The reason the saw runs better with the exhaust pointed to the side is because most any engine needs a little back pressure, a tiny bit of resistance. Like a car needing a muffler, it adds a bit of resistance

[@DaveW74TVN]

NO!

Modifying a muffler , was poaking the screen out . Good show Billy 👍🇨🇦

Buckin' Billy Brappin! Love this video, hopefully you'll do another shootout with different pipes soon!

[@lostkauz83]

👏🏻 been binging your videos on Halloween for the first time and loving it . I’m 39 with 20 years diesel ,auto and industrial truck mechanic , fabricator , welder and body man . I worked for asplundh tree company for 6 months once on mechanic hiatus , absolutely hated it , but I learned to properly fell trees . Ever since I’ve been obsessed with it as a hobby . Recently inherited my gramps old 90’s model Poulans and rebuilt the 2000 and got it running and the 2300cva which got me so high ! Now all my buddies brought me there Husq’s and you’ve handed me a great deal of wisdom 🫡 . Actually considering buying a farm Mac 380 , I know some may slam me for it but I can drop 1000$ on a pro grade 🤷🏻‍♂️ . Anyway , loving your videos sir , thanks for the knowledge !

That 372 is walkn the dog wit jus a sharp chain an a pipe!!

[@timg9448]

Hey Buckin’ just wanted to let you know that I’m about to embark on my first voyage in building a pipe for my 372. I like the designs of pipes you have here and I’m sure mine will be similar. Just bought the material I’ll need yesterday. Will send you a link to the results. Thanks brother

[@kennytheguitarfanatic054]

Buckin awesome video I just built a muffler for my husky 372 I built that saw like your husky 371. The pipe I made is something like the ironhorse muffler but with my own design different lengths and angles I used iron pipe. It woke the saw up but the H-jet is super rich for break-in . Buckin you are right the exhaust swirls in the pipe if it is right I see carbon marks in side COOL stuff.

[@steveroberts3713]

I really enjoyed this video!! Those mufflers r cool. I just got 390xp with modified muffler on it, what a lovly sound. I got lucky they stopped making them, I bought from guy that runs arborist department I deal with, he used it to only cut ice for ice fishing lol

I can tell the difference in the mufflers. I love the old Merc and Ford pickups my friend 👍

Buckin, can we see the tuning process going from stock muffler to a modified muffler? Do you need to adjust the low jet?

[@freeradical431]

Sweet pipes! Really cool design. I built a pipe for my ms250, made a hi-flow air filter and advanced the timing a little. Seems to have gained a couple thousand rpm. I like that round swirl one the best.

Hi friend, thanks for greate videos. i am going to get my 372xp ported etc. and i really want to build a key to the bush muffler, and i have a few questions😅 is there a video of the making of the key to the bush? I kinda figured out some of it by watching. But i would like to know if the "key" is welded on the outside or if it sticks inside a bit. Greatings from norway, stay safe
