3" Stainless Steel Cat-Back Exhaust System (572101) - 2010-2013 Mazdaspeed3 & 2010-2012 Mazda3
Maximize power and style on your Gen2 Mazdaspeed3 or Mazda3 with the COBB 3" Stainless Steel Cat-Back Exhaust. Engineered to minimize bends and tuck closely to the undercarriage for maximum ground clearance, this system features 3" mandrel-bent T304 stainless steel piping that splits into dual 2.5" pipes for optimal flow and reduced back-pressure. Dual chambered resonators tame harsh exhaust noise into a deep, mellow rumble without sacrificing performance, while staying within strict SAE J1169 sound restrictions (95 dB limit).
Finished with dual 4" slash-cut, double-wall rolled tips featuring laser-etched COBB logos, this direct bolt-on system includes all necessary gaskets and hardware and mates seamlessly to factory or aftermarket downpipes.
