The SURE Flow M3™ track pipe replaces the second catalytic converter on your Mazdaspeed 3. The M3 removes the severe air flow restriction that the stock catalytic convertor inhibits onto the Mazdaspeed 3. Removing this restriction improves performance and power of your Mazdaspeed 3.
Material
The M3 is constructed using 3.00″ 304 stainless steel tubing and 3/8″ 304 stainless steel CNC machined flanges. Tig welded for ultimate strength.
100% stainless steel and 100% made in America, built to last.
The Design
Our Track Pipe is a direct bolt on replacement for the secondary catalytic converter. For flexibility, it reuses the stock donut flange system to allow for necessary movement. The M3 includes all necessary mounting hardware for installation. The removal of the 2nd cat will NOT trigger any check engine lights. Track use only.
