Comments about Walker Quiet-Flow SS Muffler Assembly:

Walker exhaust system works well. Quiet. Good value. Only concern is that is hangs about 2-3 inches lower under the chassis than the OEM part so you see it from the side of the Nissan Murano.

  • Q:

    Walker Quiet-Flow SS Direct Fit Assembly PART No 49249 (Resonator/muffler/center pipe)

    Advance Auto Photo of above part apparently only shows ONE attached flange. How is pipe attached to rear exhaust piping/muffler? Note Auto Zone has same part number assembly and their photo looks like it has two flanges.

    Note that above part "should" match up with and attach to the flange on your other part
    Bosal 145-227 which is the final and rear muffler assembly.

    Thank you,

      We are sorry for any inconvenience caused. The image displayed for this Walker Quiet-Flow SS Stainless Steel Direct-Fit Assembly (Part No. 49249) is incorrect (actually it is Part No. 47771). We have forwarded a request to the concerned team and it will be rectified at the earliest. The Part 49249 has 2 flanges like you mentioned. For any further assistance please feel free to call us at: 1-877-238-2623 or visit the nearest Advance Auto store and one of our representatives will gladly assist you with any questions or concerns you may have.
