In California, it is illegal to select a catalytic converter for installation based solely on vehicle weight and engine size. The design of these systems often sees an increase in horsepower compared to the factory design of a vehicle. Because stock models try to minimise materials and maximise space, with horsepower as a lower priority.
Adding Ford F-150 Cat-Back Exhaust system to your truck is a quick, relatively cheap and easy way to extract more performance. We offer a number of high-quality systems from excellent manufacturers, so you can rest assured that whatever choice you make will look and sound like it belongs on your F-150. The Flowmaster Outlaw catback system has dual black tips that exit on the side, adding an extra aggressive look to your vehicle. Or go with a Magnaflow system for a signature rumble that everyone loves. Aftermarket performance exhausts are exhaust systems meant to replace the stock exhaust and offer more power and better tone to your engine. All our products are made from 304L "Aircraft" Grade stainless steel.
By running pipes from the catalytic converter to the muffler and from the muffler to the exhaust tip, cat back exhaust systems improve exhaust gas flow, providing small performance boosts. However, your performance gains may be limited if your catalytic converter restricts gas flow, as a catback exhaust system is installed ‘downstream’ of the converter. Header-back systems are increasingly rare, namely because of modern emissions systems. Since removing your vehicle’s factory emissions components is highly illegal, the previous two options are more common. However, header-back systems are still available for some older, pre-emissions applications. In these cases, header-back systems offer more performance and volume than cat-back or axle-back systems
