    • Q:

      what size bolts used on 2 bolt flange?
      Asked on 1/8/2014 by rob from ny

      1 answer



        Good question rob! Normally the 2 bolt flanges on catalytic converters use a 3/8" or 7/16" bolts. I do not see these flange bolts to be available in the website. You may check with a nearest auto parts store.

        The Walker Catalytic Converter - ULTRA Direct Fit (Part No. 16291) does not fit your 2001 Mitsubishi Eclipse. Please refer this MagnaFlow Direct Fit Catalytic Converter, Stainless Steel (Part No. 93193) which would be an exact fit for your vehicle. For further assistance, please feel free to call us at 1-877-238-2623 or visit your nearest Advance Auto Parts store and one of our representatives would be more than happy to assist you.
