Kooks Catback Exhaust System Ford Mustang GT | Shelby GT-500 05-09

Kooks specializes in high performance exhaust systems for domestic cars and trucks. Kooks manufactures exhaust systems ranging from Custom built headers for race applications to bolt on systems for production cars.

The Ford Mustang is an American icon of performance. For decades driving enthusiasts have revered the Mustang for its V8 engine, rear wheel drive, classic styling, and affordability. But like any other vehicle, drivers quickly look for ways to extract more power and improve the driving experience. An aftermarket exhaust achieves both of these objectives. The increased flow improves functionality by allowing the engine to operate more efficiently and produce more horsepower and torque. V8 engines tend to respond especially well to aftermarket exhaust systems because of the large amount of air they move. Along with the increased performance an aftermarket exhaust system has a more aggressive exhaust note that can be enjoyed by the driver and onlookers.

The factory catback exhaust system should be the first exhaust component to be replaced on most cars. The factory exhaust system is designed for reduced costs, ease of manufacture and low sound levels to appeal to the average consumer. A Kooks exhaust system eliminates and minimizes bends when possible, is constructed of wider diameter stainless steel piping, and features less restrictive mufflers to improve airflow and engine efficiency. Allowing an engine to flow more air means it can produce more power and torque. The decreased restriction also improves throttle response.
