Photosynthesis, for example, is a way that plants take energy from the abiotic environment and incorporate it into the biotic environment by synthesizing sugars and proteins from it.

Header-back exhaust systems replace everything from the header collector to the tailpipes. By replacing all exhaust system components, header-back systems allow you to enlarge the diameter of your entire exhaust system to flow a greater exhaust gas volume.lthough cat-back and header-back systems can deliver more power gains, there are many benefits to opting for an axle-back system. A well designed axle-back exhaust system will provide power gains over the stock exhaust but is often less expensive than comparable cat-back or header-back systems.
