Once you muff mod one saw, you will want to mod them allWat would be the pros n cons o this subject and would ther be a noticable diff in power or zip from the saw any advice would help
I think he's talking chainsaws. You will find a lot of opinions, but most agree that the cat mufflers hold heat and slow exhaust flow. If you open them up or change the muff to a non cat, it will help the saw run cooler and make more power. A lot of saws need re-tuned after modding the muffler.....need to be richer.If you are talking diesels, the only thing you will accomplish is making it louder. Unless you are making huge power (500hp/1000 lb/tq ++), freeing up the muff won't increase mpg and won't make the engine run cooler. Dyno backs this statement up.

Hahaha, oh man, I remember flipping the ole tophats over on my pickups as a kid. It was our cold air intake of the day!I think what he's asking is how much power gain can be expected. I read about guys that mod mufflers and claim big increases, but how much is the increase really. As a teenager my buddies said if I flipped the air cleaner lid on my car it would give me 10% more power. I sounded cool so they must have been right....right?
Yeah, a lot of guys did that but I never could figure out how drawing hot air from the engine compartment helped! I kept the snorkel hooked up to cool air and made sure the door worked.It was our cold air intake of the day!
More power, cooler run temps and best of all it makes them louder
Anyone knows that if it sounds faster, it is faster.Yeah, a lot of guys did that but I never could figure out how drawing hot air from the engine compartment helped!
There are NO pros to having a cat muffler on a saw, just cons.
If you're that worried about a little dirty air from the small amount of time you probably run a saw maybe you should stay in the kitchen.

Cats don't really work on chainsaws & are already phased out. I have gotten over them on cars and trucks. Used to cut em off, but they do work fine in the last 25 years or so.Not even if you & your buds are breathing the air downwind of it? Really? Lots of truthiness on this subject.
