The heart of the American Muscle Car system is the Gibson Superflow Muffler with Convergent Flow Technology (CFT). Gibson knows that increasing exhaust flow is critical for improving power, and that restriction is the biggest obstacle to increasing that flow. Gibson Superflow mufflers have some of the lowest restriction ratings of any muffler on the market.
Finally, all Gibson exhaust system components are joined with a “slip fit”, where an exhaust system component fits into the larger opening of the next downstream component. This method reduces the turbulence that is common with ‘ball-and-socket” or “flange-and-gasket” joints, which can cause power-robbing backpressure.
Gibson exhaust systems are manufactured in the USA.
Gibson® Performance Exhaust is a family run company based in Corona, California. Owners Ron and Julie Gibson started the company after they couldn't find performance products to meet their own needs, and decided to build exhaust systems themselves. Today Gibson is one of the largest aftermarket performance exhaust products companies in the world. Gibson is committed to building cost-effective exhaust systems that deliver more performance for the dollar, and make more horsepower and torque in the lower rpm range, where it's needed for real world driving. All of Gibson's street applications are 50-state emissions legal and do not affect the factory warranty.
