| Other than outside appearance, is it simply the 3 is low backpressure and the L managed backpressure? Maybe some difference in the flash suppression? |

The M4SD 3 AM can is a low pressure can. The M4SD-L is more like a low pressure conventional can. It's borderline managed in the sense of the Dual Lok 5 AM cans. The both perform really well, so it's that and a weight and appearance difference. |
