Glass pack mufflers are a great viable option for high performance applications in the racing world. They are free flowing, light weight and just enough to let the person abide by the noise restrictions many race tracks have put on different classes of vehicles.... They are tough, simple and robust. I would love to see a rotary try to melt one.
Accelerating at 2 different rates isn't necessarily going to use the same amount of fuel. Especially if you end up going in to enrichment mode during the acceleration. Turning the engine at lower revs utilizes the engine more efficiently than turning it at higher revs. You don't want to lug the engine though that will retard the timing which lowers power and the ECU will add a lot of fuel to prevent damage which would waste fuel.
