    372 muffler mod...

    Hey guys, I'm wanting to put a side exhaust port on my 372 muffler instead of the top port... tired of it burning my hand when I've got the bar buried bucking big logs. What size should the exhaust port be? Not really looking to get max power, but a performance boost would not be unwelcome...

    Is this excessive

    I’ve been tinkering with my 025 stihl I got for free locked up. I let it sit for a few weeks with deep creep in it and it unlocked. Anyways, it’s ran great for the last 2 years. I’ve started modding the muffler heavily, I’m wondering if it’s to much for this saw. It runs sweet and makes a ton of...

    Do you guys think this muffler mod will hold up?

    So a complete newbie, but trying to be creative with what i have on hand. Its a copper pipe with a pretty snug fit, and i glued it up with some steel epoxy glue thats supposed to handle heat up to 150 Celsius. I know its not pretty but do u think this should hold? It feels solid

    MS460 Muffler Upgrade

    My 460 is showing a bit of rust on the stock muffler. I figure if I replace it, I might as well upgrade it. I've never done anything but run fuel & oil through this saw. Totally bone stock. It is about a 12 year old saw now (I think. close enough) The mod that always pops up is "dual port...

    Anyone sell a ready-made modded muffler for a Makita 7900?

    Just bought a new Makita 7900 PHO for $731 shipped and was wondering if anyone makes any ready-made modded mufflers? I'm a little concerned about splitting the muffler and gutting/modding it, since I don't have a backup in case I screw up. And, if you haven't looked, OEM mufflers aren't cheap.

    Dolmar PS-352 / Makita EA3601

    Hey friends, couple questions regarding the mentioned saw. Can i upgrade it to .325 ? How well does this saw respond to a muffler mod? I would most likely enlarge the existing outlet but not quite sure how much. What would be the meanest chain for that saw in 3/8 lp pitch? At some point this...

    I ported the Echo 2511T & muffler mod info

    Finally decided to tackle the little echo saw. I really didn’t think much of the saw stock. Slow chain speed, wrong bar and chain setup when stock. Chattering was an issue. It worked fine for cutting small limbs when up in a tree but that’s about it. Here’s the muffler part There really isn’t...

    Stihl 015 electronic conversion, strobe light timing?

    Picked up an 015 from my dad, he couldn't remember the history on it. Took it home, fueled it and no start, looked like no spark so I read, found and did the points to electronic conversion. Cleaned the air filter and threw a new plug in it also. Saw started on 5th or 7th pull and ran, cut...

    Echo CS-341 Muffler Flow bench testing

    Howdy, Been a little while so I thought I would post today's shop fun. My trusty little Echo CS-341 was in need of some spring maintenance so I took the opportunity to upgrade the muffler. This saw came with a catalyst muffler which always has seemed restrictive. Turns out the CS-3400 saw...

    044 muffler mod

    Not much of a thread but I am looking to mod my 044 muffler it has the divider with the 3 big holes, does it go to pry that out or does one need to cut it out? Also, behind the divider is a metal box with smaller holes surrounding the inlet to the muffler. Is it best to cut that out completely...

    Stihl 029 Super Muffler Mod and the Quality of Stihl

    I have a Stihl 029 Super that I bought new approximately 15 years ago. I have cut A LOT of wood with this saw. I've never cut the saw any slack. I've been threatening to do a muffler mod on it for a few years now and today I finally got around to doing it. I removed the limiters on the carb so...
