| I am not a mechanical engineer, but I have fooled around a little with race cars. I am not real sure about the smaller engines but I think there is a little math involved when you are dealing with exhaust. You have to take into consideration the back pressure that a muffler produces when an engine is running. Too much back pressure or not enough could mean the difference between a crappy running engine, or ruining one all together. The inner dimensions and flow rate are pretty critical to an engine being happy. But I would be interested in knowing if you could build a custom muffler. Especially like you say for scale apps, not to mention having one that was much quieter.
