Since 2-stroke engines are notoriously bad polluters, is there such a thing as an exhaust filter? Forgive my ignorance on engine-related topics, but I would imagine restricting the airflow by any kind of forced air filtration would de-tune the pipe, resulting in engine inefficiency. I'm wondering if any other methods of cleaning the exhaust air exist. I don't recall seeing something like that. 4-strokes seem to burn pretty clean but 2-strokes often leave a cloud of smoke. Thanks for any feedback.
