Performance Exhaust System's Save Gas

[LoveMustangs.com]

You may not have known it, but you can save gas by upgrading your car, truck, van or SUV to a performance exhaust system. Using “save gas” and “performance exhaust system” in the same sentence may seem like a contradiction in terms, but it’s a fact. It all has to do with engine efficiency. The real function of a performance exhaust system is to get the most from every drop of fuel. Whether you get “more power” or save gas depends on how you drive and how you tune your vehicle. The choice is yours.
