Stihl 025 Muffler
« on: October 24, 2022, 10:31:21 PM »
Hey everyone, I'm new to the forum. 
I have a question for the two-stroke gurus. 

I have a very nice little 025 I got for free and I was looking to modify the muffler. Most videos on YouTube simply gut the muffler and open up the front port. I've done this before with varying results.

My idea was to make a dual port muffler with a solid front. I've read that its important for a two stroke muffler to have a front "wall" in order to reflect sound waves back into the exhaust port. Is this true and if so, would a dual port muffler offer better performance?

Yeah I know it's just an 025 we're talking about, but the theory of it is what interests me.
