The document discusses BMW exhaust systems and how to clean and maintain them. It first explains how BMW engineers designed the exhaust to reduce back pressure and increase airflow into the engine. This allows the engine to produce more power while using less energy. It then provides a list of recommended equipment for cleaning BMW exhausts, such as cleaning products, microfiber towels, and steel wool. Finally, it outlines the steps to clean the exhaust, which include applying cleaner, scrubbing from the inside out, polishing the tips, and buffing with a microfiber towel after using steel wool.

1. BMW EXHAUST
How to clean maintain this beast with care

2. Like a world-class athlete, the BMW's engine needs increasingly
more oxygen as it reaches its physical limit. For this need, BMW
engineers looked to the other end of the vehicle, namely the exhaust
system. Overcoming this restriction, or back pressure, forces the
engine to work harder, using its energy for something besides
moving you forward.
Hence enter BMW exhaust, this solution produces an outflow of
exhaust gases that is so free (though still under control) that it
markedly reduces back pressure. The flow is free enough, in fact, to
actually pull more air into the engine. So while it's saving power at
one end, it's increasing power at the other.
