All right guys, this takes a little explaining. Hyway calls this an ms440/460 muffler without screen. But as you can see in the pictures, it absolutely has a screen on the single port. It's a nice well-made muffler, but I have no idea why they say without screen. These are kind of nice to mod if you're going to put a pipe in the front, whereas the dual Port muffler, which also has two screens, is harder to do any modifications to the front because of that second Port.
