Description

The COBB Gen2 SS 3-inch Cat-Back Exhaust for the 2010–2013 MAZDASPEED3 uses a high-clearance stainless-steel layout to reduce back pressure while keeping exhaust sound controlled and refined. It fits the factory exhaust path and works with the stock or a direct-replacement downpipe.

  • 3-inch mandrel-bent piping to a dual 2.5-inch split
  • One primary and one secondary resonator for a mellow exhaust tone
  • Dual 4-inch double-wall slash-cut tips with laser-etched COBB logos
  • Works with COBB, stock, and direct-replacement downpipes
  • Includes gaskets and hardware; uses the stock doughnut gasket at the downpipe
  • Designed to stay within SAE J1169 sound restrictions
  • Product code: 572101
