Product Details

Eastern Convertors 40913 is made for 2006-2008 Mazda 6 front left radiator-side applications where the exhaust manifold and catalytic converter are serviced as a single unit. The DIRECT FIT line focuses on OE-matched dimensions and fitment, while the ECO III catalyst and NANO substrate chemistry support efficient exhaust treatment in a compact manifold-converter assembly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Repair Symptoms

• Check engine light related to catalyst efficiency or exhaust flow
• Cracked or leaking exhaust manifold assembly
• Failed catalytic converter substrate
• Exhaust noise from manifold or flange leakage
• O2 sensor fault codes tied to the front left exhaust section

Installation Notes

Verify the vehicle is a 2006-2008 Mazda 6, front left, radiator side before ordering. This assembly uses a 6-bolt welded inlet, a 2-bolt welded outlet, and two O2 sensor ports. Confirm emissions requirements before installation; not for sale or use in California, Colorado, Maine, or New York for vehicles with California emissions.

Quality Assurance

Eastern Convertors uses advanced manufacturing methods, including automated workstations, spinner welding equipment, and high-speed production lines, to maintain OE-dimension consistency and controlled production quality.
