      Comments about Bosal Exhaust Products:

      Bosal 256-446 is a expensive "special order" exhaust gasket - received and compared to Walker exhaust gasket 31640 appears to be the same in construction, material and quality. The expensive Bosal gasket also requires additional shipping charges. Both gaskets are marked "Made in [*]". The Walker gasket is available in most stores, is much cheaper and does not require shipping charges. It is available much faster. If you need this size gasket go with Walker 31640 (SKU 20380824)

      • Q:

        1. What is the distance between the center of the two bolt holes?

        2. What is the Diameter of the center hole?

        These measurements are needed as more than one size of flange may be installed. (Example 2004 Nissan Murano has two similar shaped flanges but at least two on the same SUV are of different sizes, so even when searching "exact fit" size does matter.)
