    Gibson Cat-Back Exhaust Systems deliver more power from 2000-4000 RPM than other exhaust systems. Other systems claim more power, but in the 5000-6000 RPM range, which is rarely used by street vehicles. Their patented Superflow™ design promotes scavenging and reduction of turbulence. All Gibson Exhaust Systems are made with mandrel bent tubing for the least restriction possible.

    Dual Extreme Exhaust
    For the enthusiast who wants an aggressive and powerful sound with unique looks, the Dual Extreme Cat-Back Exhaust is it. Exits behind rear tires at an angle (will not fit with fifth wheel trailer hitch). Dyno tested to increase power, improve acceleration, and maximize passing/towing.



    Features:
  • Maximum Torque & Horsepower Gains At Low RPM
  • Mandrel-Bent Tubing
  • Increased Fuel Economy
  • Heavy Duty Aluminized Steel
  • 50-State Emissions Legal
  • Made In The USA!
