Gibson 5569 - Gibson Split Rear Aluminized Cat-Back Exhaust Systems

Improve exhaust flow & create more power where you need it!
Gibson Cat-Back Exhaust Systems deliver more power from 2000 to 4000 RPM than other exhaust systems. Other systems claim more power but in the 5000 to 6000 RPM range never used by street vehicles. Turbulence exists at every point an exhaust gas "pulse" enters or exits an exhaust component. Gibson reduces turbulence to the absolute minimum in two ways: their patented Superflow design moves exhaust gas out and their slip-fit joining of each pipe into the larger opening of the next pipe. Slip-fit is superior to ball/socket or flange/gasket joining because substantial power-robbing turbulence can be created in such joints (a misaligned socket or gasket can actually make more backpressure than stock systems).
