More like a kit than a single part, many of Dorman Exhaust Manifolds include gaskets and downpipe hardware for easier installation.In addition to offering our manifolds as complete kits, our OE FIX improves upon the original design. We have upgraded the material to a stronger more heat resilient material called ductile iron for increased durability and to prolong the service life of the part. Since this part is a direct replacement, the exact fit adds another layer of efficiency and convenience.
