Gibson Exhaust Dual Rear Exhaust System

Gibson Exhaust Dual Rear Aluminum Exhaust System

Gibson Split Rear Exhaust System
For the enthusiast who wants an awesome look and aggressive powerful sound this split rear bolt-on cat-back exhaust is for you. Gibson's exhaust systems decrease backpressure, allowing the engine to produce more torque, increase horsepower. Typical gains average of 15-20 horsepower. On some vehicles the spare tire may need to be relocated or removed. Works with most bumpers, roll pan and trailer hitches. Not recommended for towing, because carbon monoxide may be drawn into the interior rear of a vehicle when an exhaust pipe directly exits to the rear of the vehicle. Exhaust can be louder under towing conditions.
