Review on Dorman 674 838 Integrated Catalytic Converter by Steven Asthana
Converter fits manifold perfectly - works as expected
Fits a 2003 Mazda 6 3.0 V6. As advertised this was a direct replacement and works perfectly. Includes manifold and exhaust gasket and new exhaust bolts. Although it just fitted, the heat shield welded on was not accurate and additional effort was required to reattach the head bolts. At the same time I installed new oxygen sensors upstream and downstream. The Revain's price saved me a ton of money compared to OEM and local auto parts stores. I will post an update of any changes.
- Cast iron or stainless steel tubing construction prevents warping and/or cracking
