Effect on Mileage
The majority of individuals do not consider the mileage effect of a muffler. A common misconception is that a muffler has no effect on mileage.

The Flowmaster 40 utilizes more fuel to achieve that powerful sound, which makes it less efficient for better mileage. Instead, it may result in a reduction in your mileage.
