4. Free Flowing Exhaust System

exhaust_system_en

This is once again another greatly misunderstood after-market upgrade for vehicles. A free flowing exhaust system can increase the fuel economy of a vehicle, simply by improving the overall efficiency of the engine. A free flowing system does not mean that the exhaust has to be loud, it just needs to flow better. Sound has little to do with a properly tuned exhaust. What we’re after here is efficiency, and the greater the efficiency of an engine, the less fuel that will be necessary for the engine to perform at its original intended level. However, any increased fuel efficiency attained, can be lost due to poor driving technique, which brings us to the next method of improving fuel economy.
