Walker 31640 High Quality Exhaust Gasket
The Walker gasket 31640 is equal in quality to the much more expensive "Special Order" Bosal 256-446. Both gaskets appear to be of the exact same material, design, and quality. Both are marked "Made in India". The Walker gasket is well made and a good choice as a exhaust gasket. It is available in stores and does not require a long (week or so) shipping wait that the Bosal gasket does.
Bottom Line Yes, I would recommend to a friend
