    Gibson GM Cat-Back Exhaust Systems improve exhaust flow and provide more power from 2000-4000 RPM than other exhaust systems. Power-robbing turbulence exists at every point that an exhaust gas "pulse" enters or exits exhaust components. Gibson Systems minimize turbulence in two ways: patented Superflow™ technology assists exhaust gas in its flow out, and slip-fit connections reduce backpressure at the exhaust's joining points (i.e. each pipe fits into the larger opening of the next pipe).

    The quietest system Gibson offers, these single swept-side exhausts are stainless steel and produce a deep, throaty tone outside with only a slight increase over stock sound inside. Gibson Exhaust Systems feature mandrel-bent tubing for consistent flow throughout the system with the least restriction possible. Superflow™ Mufflers have a chambered/baffled structure to deliver dramatically higher exhaust flow compared to packed or screened mufflers. Too large a pipe without the proper muffler decreases low-end torque but increases top-end power. Gibson builds their exhaust systems to flow as efficiently as possible. Typical gains average 15-20 horsepower. Swept-side systems are engineered and tested to improve acceleration, towing, passing, and hill climbing. Fuel economy may also improve as the engine becomes more efficient.
