Some, many, communities have ordinances against excessive noise. Our club will not permit removal of the baffles from mufflers. We just don't want to lose our flying field. The area is owned by the state and I am sure that if complaints come in about noisy aircraft flying overhead, they will cut us off.

Why is it, then, are those low-riders with three foot wide woofer speakers get away with what they do? And, while on the subject of noise, think about that harley chopper that went by you without any mufflers at all. But, we RC'ers have to tow the line.

Just consider the noise issue before you start pulling out those baffles. It just ain't worth 300 RPM gains.
