Released for the new turbo charged Chevrolet Cobalt SS is this catback exhaust system from Agency Power to help create an incredible sound and power increase. The exhaust system is all T304 stainless steel featuring robotic TIG welds and a complete polished finish. The system connects to the factory catalytic converter with a thick flange and includes a resonator to reduce in cabin noise. The muffler and mid pipe section fit together with a slip fit design for easy fitment. The exhaust fits with all the factory exhaust hanger mounts and features a straight through round canister design. The 4 inch exhaust tip is elongated to sit nicely out of the rear bumper exhaust opening. This exhaust system was tested on our Mustang Dyno and achieved approximately 10 horsepower gain. With horsepower also came improved throttle response, and low end torque gains. This exhaust is designed to work with the 2008 and up Chevy Cobalt SS sedan.
