89 tioga arrow ford exhaust leak

i have a 89 tioga arrow ford e350 with a 460 v8 has a very bad exhause leak looking for a after market header that will fit and is ca smog legal or would it be best to replace with stock exhaust manifolds?

    Let me see from 89 to 15 is 25 years if he gets 1/2 the service out of the replacements he will be just fine.

  • You could have broken bolts, however just replacing them may not solve problem as the original exhaust manifolds could be warped.
    Kind of expensive for real good headers for your year. The standard ones here should work just fine. (verify that they are smog equipped) You may still have to fix bolts.

  • Is the leak due to manifold bolts busting loose - common problem in some of the E350's. If so you can drill out/replace those bolts.
