Just call Slimline...


Last week I found a Slimline Pitts muffler for an OS 120 4-stroke. I wanted to use it for my YS 140L, but didn't know if it would fit. I called Slimline, and I talked to a guy named Bill I think. He was very helpful in explaining me what the differences between the YS and OS muffler were, and how to fit the OS muffler on my YS engine.


So I'm sure he will tell you what muffler you need!
