Key Features
- Direct-fit manifold converter for select Mazda 3 and Mazda 3 Sport models
- Stainless steel converter body for exhaust system durability
- Integrated exhaust manifold design matches the original equipment configuration
- Round inlet port shape with 4 inlet ports and 1 outlet port
- Flanged outlet design with included outlet mounting hardware
- Natural finish and regular grade construction
- Sensor port count: 1; air tube count: 1
Application Details
This catalytic converter with integrated exhaust manifold is engineered for 2010-2011 Mazda 3 and 2010-2011 Mazda 3 Sport vehicles with California emissions. Part number 674-277 is a direct replacement option for drivers needing an OE-style manifold converter assembly on these Mazda applications. Cross-reference part numbers for the same application include 50769 and LFE42050X.
What It Helps Address
- Failed catalytic converter efficiency codes
- Exhaust leaks at the manifold-to-exhaust connection
- Cracked or deteriorated manifold converter assemblies
- Emissions test failures on California-emissions vehicles
- Check engine lights related to converter or sensor performance
Installation Notes
