Very nice IronHorse! That wood-pile doesnt stand a chance with that saw running nearby! Thank you for showing her rip. Take good care!

Very nice to see this working well. Those pipes are very nice!

OMG! WOW!!!!!!!....SHE CUTS EH!

Saw runs fantastic, nice job Harvey! Cant wait to see how it runs ported.

Wow power to weight is amazing. Ported holy smokes hang on Harv. Love ya Ironhorse and thank you CPI. Love it. 🌲❤️🌲👊🪓

Awesome!! Thats freakin sweet Ironhorse love the videos and builds you do!! 👍👍

That pipe is awesome! Sounds great too!

Cool to see that front part of the pipe changing colours for the first time . Looks killer . Would love one of these

running good and sounds awesome with that pipe.cant wait to see how its running after porting

Very nice! I am impressed by the power without a lot of noise!

Impressive pipe! Thanks for sharing.

Loved the one I got for my customer. Excellent pipes!

Truly a Work of ART!! Very nice build Harvey😁

You're making dreams come true Harvey. I love everything about you Ironhorse ❤ thanks for sharing this

Nice job great video Harv can’t wait to see it when she’s finished

Harvey, I agree It's not a loud pipe...runs hot and sounds kool. Good video thanks

NASTY,,GREAT SAW GOOD JOB HARVEY,,HOPE YOU BARB AND CULLIN ARE WELL STAY SAFE BUDDY

Wow! Ive learned a lot from your channel. its been fun we have some stuff in common, so its nice to see you took it to the next level in performance building. love your work. My first motorcycle age 7, Honda Cb50? folding handlebars with balloon tires, my parents bought from my Great Uncle. Then an XR75, and later about a 76"-78'? Honda Elsinore CR 125 that had an FMF head and pipe on it with a full Dan Gurney sprocket set. The Elsinore also had a reed upgrade, I think Toomey or M. Smith? I ate up a lot of RM250 back then believe it or not in/around the Carona _ Lake Elsinore _ Hemet area, back when you could pull off the freeway and unload and shoot out into desert hills. Thanks to your old stories you have brought up a lot of my younger life as well as schooling me.

That’s a beast!!!!!!! Awesome job Harv!!!!!!

Great awesome vid Harv she runs good with basically a bb on it , luv the pipe and looks good to,👍👍

Cool! That cuts real quick.

Holy smokes Harvey! That sucker rips! Can’t wait until it’s ported. Thanks my friend.

Thank you for sharing this.

That is impressive, and looks like a lot of fun to run !

Wow!! Haven't seen you this excited in a long time😁 Little jump in your step👍

Rocky Mountain chainsaws and CPI Pipes love it when someone use the pipe the way it should be. I would know Rocky Mountain chainsaws and I just watched to together. They are very happy you like it

Wow what a ripper . Your a Wildman Harvey.

CPI has been making pipes forever…. Always was the pipe to beat on Yamaha banshee, I imagine they’ll dominate the chainsaw world.👍 cuts great!

that's a very cool saw. i love the pipe! im inspired to do a few mods myself. it looks the business for sure and sounds insane 😄

Pretty sweet..that pipe makes it even sweeter...👍👍

Love this stuff

Holy S - that thing is awesome !

Hot damn Harv She screams, Great job on that one! Cant wait to see more:)

Wow Harv that thing pulls. I can’t imagine this thing once you put the majic to it.

Be scared to fell with her, darn thing pull the tree off the stump haha, I'm workin on what we talked about bud, I'm thoroughly excited how once you get it you get it and to have someone like you willing to share freely the years of knowledge with us

Yes, Yes, and Yes she rips. Great vid. Be safe and be careful.

i think the combo you have produced is a excellent product and is going to be even better once you start porting. id like to know how its going to work for a professional guy but seems like your really on to something with this guy.

Pipe really looks good

Awesome! That thing gets it.

Thats a mean saw and i cant wait till ported oh my its gonna be crazy

Shes freakn stout sir amazing work.

Amazing Pipe 😮😮😮😀

Jeez Louise, what a cutter!!!

Sounds good!!!!

Your hair looks good!

I love when a saw doesn't bog down when putting some weight on it.

Harv, glad to see that ton of Work and Thoughts running like a Beast. How many Hours did you spend in Thinking and Building? Did you tell the Numbers? May i forgot them. Appreciate your Work, that is a something i would like to have in my Hands. But Germany is to far away . I would like to see her in Hardwood, cause we have almost Hardwood around here to feed our Stoves. I‘m hungry for more of your Builds! Stay healty and have fun at Sawfest.

Man that's nice with some more to go taboot

I read the old 2 stroke scooters often used a straight megaphone/cone style expansion pipe because it provided the most benefit/power at wide open throttle since they're rode at WOT most of the time.....And that dirt bikes use a curvy shaped expansion pipe for added power throughout the whole throttle range, plus ground clearance. They could easily build 2 stroke dirt bikes with a scrambler style straight expansion pipe. That'd have plenty of ground clearance but would only mainly benefit when hitting WOT....I see some scooter pipes that are mostly straight with some slight bends & curves. I'm not sure if it's only for clearance issues. Or if they're trying to make the pipe create a bit of mid range power without taking too much away from WOT.

No, I don't think so. What I have read (Gordon Jennings) is they use the megaphone style exhaust before the curvy expansion pipe, with the reflection cone, was invented (in East Germany). The megaphone did give more power than a straight pipe but the addition of the reflection cone was superior in every way to only a megaphone. How steep the angle of the reflection cone is determinates how broad the rpm range the resonator pipe will work in. Steep angle = strong reflection pulse / narrow power band. And resonator pipe usually use a stinger pipe (which is missing or hidden inside on the resonator pipe in this vid) the diameter and length determines how strong the pipe will supercharge the engine, more restriction = more power -until the engine overheats.

Nice pipe nice short tail and a larger outlet it’s gotta work.

Take my hat off to you Harvey💪💪

Holy chit! Wicked Harv! Wonder what that motor would do in a little pit bike or one of those little ice chest go kart rigs! That will peel ur muffin cap back! Mint👌

I’m assuming the stinger is on the inside of the rear cone? Be interesting to know how long and what diameter and what messing with those two measurements might do to change how and where it comes on. She sounds like it’s tuned pretty good right now!👍🏻💪🏻🇺🇸

@nhytg376tgyuu765gjmg

The length of the expansion chamber determinates where it comes on. The dimensions of the stinger determinates how hard it will charge the cylinder. More restriction equals more power but to much restriction will overheat the engine. It's a very fine line between max power and overheating.

Very impressive. I wonder how it'd fair against a McCulloch Pro Mac 850 if they both ran 36" bars! Definitely a chainsaw to test your ear protection with :) Nice job, brother!

Like always amazing content, God bless you your family and all of your followers, that includes me lol, with love peace and saw Grease Jay small

Even Rossi would be proud of that pipe on his bike!

Harvey that saw eats👍

Holy moly

Nice! Once it's ported it will male a man drool!

Wow! Nice! I have to go back and get caught up on this build. 3/8 or .404? Take care and best wishes.

I need help with my grandpa’s pioneer P60. The crank was broken on the clutch side and was welded up and repaired. I don’t think it will last very long though. I would love to get a different crank for it but, as you know, I can’t just get a new one. If you could help me locate one I would greatly appreciate the help! Thank you for sharing your knowledge threw KZread.

Hahaha, that wasn't ported.... ok. Wow. Looking frwd to this one! Take care Harvey!

Curious to know how the return impulse on the exhaust works on such a small cc engine at high RPM. I would think the pipe was too large and too long to give the right impulse. Just my thought.

Possibly a silly question because I feel like it answers itself...but do you think that pipe will hang with that saw once it's ported or is the added airflow going to be too much for the pipe?

Plenty of torque still beast!! Nice 1 harv how’s the garden this year

Hi . I am wondering if someone can recommend a velocity stack for a Husky 61 please? My stock air filter sucks in a lot of dust

Do you sale any 572xp ported mufflers?

In the words of Joe dirt, "dang"

Ill bet that if you want noise, add a 4 inch piece of pipe at the end of that chamber.

Time to do some porting now?

That's a muffler burn 🔥 waiting to happen.

Sounds bit lean I’d be bringing that high speed needle out a bit, it’ll grab a ring otherwise
