Frequently Asked Questions Ask APW
If the exhaust is fitted with aftermarket parts, will this void the truck's warranty?
Answer: No. Even if the exhaust system has been replaced with aftermarket components, the warranty is still secure due to the Magnuson-Moss Warranty - Federal Trade Commission improvement Act of 1975. In fact, it will be illegal for a dealer to deny OE warranty on the basis that a defective exhaust has been replaced with an aftermarket product. If the dealer fails to honor emission or warranty claims because of this, reporting this to the US Environmental Protection Agency or the Federal Trade Commission is highly advised.
When should Ford F-150 exhaust systems be checked for maintenance?
Answer: The muffler and other exhaust system parts in the F-150 are not typically scheduled for regular checkups or replacement by Ford, but if there are any problems or any discrepancies in the exhaust, it must be checked immediately. Some warning signs that may lead to exhaust problems include punctures in the muffler, loud thumping or clinking noises, thick, billowing exhaust gas, and frequent overheating of the engine.
Will a brand-new exhaust system improve the horsepower output?
Answer: It depends on the type of exhaust system and the ability of the fuel management system in the F-150 to provide the right amount of fuel to match the airflow. But in most cases, a brand-new exhaust can result in around 5% to 15% increase in airflow. High-end performance exhaust systems designed for racing applications can produce an even higher horsepower output.
Will a newly installed aftermarket performance exhaust in the F-150 bring improved mileage?
Answer: It will, provided that the exhaust system that has been installed is of good quality. High-quality exhaust systems move the exhaust gases from the engine more efficiently and at a higher temperature than a standard factor exhaust. This in turn leads to gains not only in horsepower but also in fuel economy, particularly at cruising speeds. Trucks such as the F-150 can especially benefit from aftermarket exhaust parts.
