Kooks Catalytic Converters Dodge Challenger 5.7L Hemi 05-10
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 Hemis reputation among muscle car fans is almost legendary. Its success at the track and on the street rival any engine past or present. For decades driving enthusiasts have loved the Hemi for its power, torque, simplicity, and aftermarket support. When Chrysler brought back the Hemi engine in its modern form automotive enthusiasts were thrilled to have old school power with modern technology. But like any other engine, drivers are always looking 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. Along with the increased performance an aftermarket exhaust system has a more aggressive exhaust note that can be enjoyed by the driver and onlookers.
A Catalytic Converter acts as a screen burning remaining fuel that is unused while leaving the engine. The catalytic converter is one of the most restrictive parts of the exhaust system, greatly limiting the amount of horsepower and torque that can be extracted from your engine. Kooks high flow catalytic converters are designed to bolt on to Kooks headers and increase exhaust flow over the factory catalytic converters. Catalytic converters are often a bottle neck in an exhaust system that has aftermarket headers and a catback system. Eliminating this weak link will allow your other exhaust modifications to be utilized to their full potential.
