ported 441

[talltreeclimber]

I just finished up porting my MS 441 Magnum. The 441 is a great saw to begin with, with its air filter system it gave the engine alot of air. More air was a good thing but the exhaust with its small outlet hole and spark arrestor was very restrictive. So i removed the spark screen and bored out the hole to about 3x the original size, then cut a 3/4 inch pipe at an angle to cover the oval hole an welded it on. Then i sanded it down smooth and painted it with 1000 degree black grill paint an put it on... SOUNDS AWESOME! It has better throttle response an ALOT more power!
