Does Flowmaster Increase Gas Mileage

Does Flowmaster increase gas mileage? Yes, installing a Flowmaster muffler in your car will certainly increase the gas mileage because Flowmaster exhaust systems are made to provide an easy passage of gas to and from your vehicle by pushing used or exhaust gas/fuel out of your car immediately they are used, freeing up the pathway for the flow of new oil, enabling the engine of your car to run as smoothly as possible.

What is a Flowmaster Exhaust Pipe?

Flowmaster Exhaust System is a high-performance aftermarket exhaust system used for cars – sprint or sports cars especially. It is manufactured by the famous Flowmaster, Inc., a company established in 1983 by a man named Ray Flugger.

The idea behind the creation of this top-of-the-line exhaust pipe was to reduce the noise generated from the California Sprint Car engine to the barest minimum in a way that will not affect or sacrifice the performance that was provided by the normal, traditional, conventional exhaust systems.
