Walker Ultra EPA 16391 Direct Fit Catalytic Converter with Integrated Exhaust Manifold for Toyota FJ Cruiser

Excellent product ; with minor flaw that one of the holes in the flange that connected to the rest of tailpipe , only one side was threaded . But a good die set and a little oil and probably solved . Perfect fit otherwise ; price was very reasonable and arrived in good time.

Placed this walker manifold on a 2005 Toyota 4Runner. Then drove a 400 mile trip. So far it has held up well. The welds looked good and the mounting plate is heavy duty. Time will tell if it lasts. Could not afford 3 times the cost for OEM, if you can OEM is the best way to go. Check engine light has remained off. Make sure to get the stud nuts tightened down well.

Worked perfect on my 2009 Tacoma - no CEL afterwards. Got my truck to pass provincial inspection no problem! Would recommend this as an alternative to OEM manifolds. Only fault would be gasket was a little mangled inside the box, but still worked.

The flange on the new one is so much thicker than the original… They would’ve worked if the flange was as thin like the original. Flange thickness will not allow for nuts to go on studs . No phone number for manufacture for shop to get assistance from vendor either .
