Gibson Performance is the industry’s #1 leading manufacturer of street legal, high performance exhaust systems for trucks, SUV’s, diesel, offroad, side x side and motorhomes. Gibson delivers its’ power in the 2, 000 to 4, 000 rpm range. Other competitive systems claim more power by using the higher 5, 000 to 6, 000 rpm range. . . this rpm range is never used by street vehicles and seldom by high performance vehicles. We design our products in our fully equipped R&D center with multiple engine and chassis dyno’s along with flow bench and audio test equipment. Each new component must pass both quality and performance evaluations prior to a manufacturing commitment. Gibson performance exhaust systems will give your vehicle more of what you’re looking for in a performance system.
