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.

Key Features

  • T304 Stainless Steel Build: Full 409-grade mid-pipe and T304 stainless steel muffler and tips resist corrosion for long-term durability in all conditions.
  • 3-Inch Mandrel-Bent Piping: Smooth bends maintain velocity and reduce restrictions, supporting higher boost levels and freeing up power across the RPM range.
  • High-Flow Resonated Muffler: Enlarged internal volume quiets harsh frequencies while amplifying turbo whistle and exhaust burble for an engaging drive.
  • Dual 4-Inch Polished Tips: Angled slash-cut design integrates seamlessly with the bumper for a clean, factory-plus appearance.
  • Bolt-On Design: Clamps and hangers match OEM mounting points for straightforward replacement without fabrication.

Product Notes

  • Retains factory catalytic converter position for emissions compatibility where required.
  • Clean with mild soap avoid abrasive cleaners to preserve finish.

Installation Notes

  • Professional installation recommended.
  • Requires basic hand tools torque clamps to 40 ft-lbs and verify clearances after heat cycles.
  • Uses factory rubber hangers and stainless clamps no welding or cutting needed.
