The amount of horsepower gained from installing a cat-back exhaust system varies by vehicle and the system’s design. However, when combined with other performance enhancements, the gains can be more significant. The primary goal of a cat-back exhaust is to reduce back pressure, allowing your engine to breathe better and operate more efficiently. The factory exhausts come in mandrel bent tubes made of stainless steel or aluminized steel. Besides offering longer durability, the construction also ensures there’s free flow of gases. To improve this, you can opt to replace some parts of the exhaust system using aftermarket performance exhaust systems.

Shelby also gives the truck some off-road chops by installing a BDS 3.0-inch lift kit, Fox 2.5-inch internal bypass dampers, and performance rear traction bars. The truck also sits on a set of 22-inch Shelby wheels wrapped in 35-inch all-terrain tires. The new 2024 Ford Shelby F-150 packs up to 785 hp, or more power than many supercars. That's with an available supercharger for the truck's 5.0-liter V-8. Buyers can also opt for a naturally aspirated version where the V-8 keeps its stock 400-hp rating.

Although phosphorus is no longer used in gasoline, it (and zinc, another low-level catalyst contaminant) was widely used in engine oil antiwear additives such as zinc dithiophosphate (ZDDP). Beginning in 2004, a limit of phosphorus concentration in engine oils was adopted in the API SM and ILSAC GF-4 specifications. Although catalytic converters are most commonly applied to exhaust systems in automobiles, they are also used on electrical generators, forklifts, mining equipment, trucks, buses, locomotives, motorcycles, and on ships. They are even used on some wood stoves to control emissions.[5] This is usually in response to government regulation, either through environmental regulation or through health and safety regulations. Custom setups, especially for vehicles that do a lot of off-roading are also available.
