When we raced shifter karts is was in a city park in Phoenix where the sound limit was (IIRC) about 80dB (same as the street). The track required everyone to use an "intake muffler" to kill the sound. We had a kind of fat round thick softish plastic canister that really works without measurably affecting power. I'm sure you can find them on any karting website. Stan

One day when we went over with the K&N's, we switched to the foam filters and got past the sound meter! TonyJ built a very nice cover for his carbs with great results with foam material on the outside of the cover. Bob Jordan #5 Fmod NER SCCA --------------------------------- The fish are biting.
