Gibson Cat-Back Exhaust Systems create more power from 2000-4000 RPM than competitor systems. Gibson Systems minimize power-robbing exhaust turbulence in two ways: patented Superflow™ Mufflers (chambered/baffled to deliver dramatically higher flow compared to packed/screened mufflers) and slip-fit connections (pipes fit into each other to reduce backpressure at joining points). Gibson Exhaust Systems use mandrel-bent tubing for consistent flow through the system with the least restriction possible.
The most aggressive exhaust Gibson offers, these aluminized steel Super Truck Systems produce a powerful race truck rumble (noise level may exceed 95-decibel standard) with impressive improvement in acceleration and performance. Average dyno-tested gains were 10-15 horsepower and 15-20 ft/lbs torque. Super Truck Exhaust Systems are not recommended for heavy-duty towing, and they feature dual rectangular tips.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
