Cobb 2010-2013 Mazdaspeed3 Gen2 SS 3in Cat-Back Exhaust
The Cobb SS 3in Cat-Back Exhaust (MPN 572101) replaces the factory exhaust from the catalytic converter rearward on 2010-2013 Mazdaspeed3 models. Mandrel-bent 3-inch piping and high-flow muffler improve exhaust scavenging for better throttle response, horsepower gains up to 8 whp, and torque increases up to 12 ft-lbs when paired with tuning. Drivers enjoy an aggressive turbo spool sound and deep tone without interior drone.
