Efficient Emissions Solution for Your Car

This catalytic converter is the perfect replacement for your automotive needs. Its seamless integration ensures that you'll be able to enjoy a cleaner and more efficient driving experience... The sturdy build of the device ensures years of uninterrupted use without any hassles. However, the converter might take a while to warm up and optimize its performance..

Pros
  • Efficiently converts harmful emissions into less harmful ones, reducing environmental impact.
Cons
  • May not meet emissions standards in all states, potentially limiting its use and resale value.

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.

Pros
  • Cast iron or stainless steel tubing construction prevents warping and/or cracking
Cons
  • write later
