Dorman 674-048 Catalytic Converter with Integrated Exhaust Manifold - Front
Dorman 674-048 Catalytic Converter Manifold
Dorman 674-048 is a catalytic converter with integrated exhaust manifold for front-position applications on select Chevrolet, Cadillac, and Buick vehicles. It is built to match original equipment dimensions and mounting points for a direct replacement on the listed applications.
Key Features
- Integrated exhaust manifold and catalytic converter design
- Stainless steel converter body for corrosion resistance
- Flanged outlet with one inlet and one outlet
- Two sensor ports for emissions system integration
- Includes inlet gasket, outlet gasket, bolts, and washers
- Natural finish with regular-grade construction
- OE-style fitment for front exhaust placement
Detailed Description
This manifold converter is engineered for direct replacement on specific front exhaust applications, including 2016-2020 Chevrolet Impala, 2016-2019 Cadillac XTS, 2014-2017 Chevrolet Impala, 2013-2016 Buick LaCrosse, 2013-2015 Cadillac XTS, and 2012 Buick LaCrosse. The Dorman 674-048 uses a stainless steel converter body, an oval inlet port, and a flanged outlet to match the original exhaust layout on the listed vehicles. This part cross-references BBB Industries 52001 for the same application.
What It Helps Address
- Cracked or leaking exhaust manifold housing
- Restricted catalytic converter flow
- Exhaust leaks at the manifold or flange connection
- Check engine light concerns related to catalyst efficiency or sensor readings
- Failed emissions inspection caused by a damaged front exhaust assembly
Installation Notes and Tips
Verify front-position fitment by year, make, model, and emissions configuration before installation. This part uses two sensor ports and a flanged outlet, so confirm the vehicle’s exhaust routing and sensor locations match the original assembly. The package includes inlet and outlet gaskets plus outlet mounting hardware; inlet mounting hardware is not included.
Quality Assurance
Dorman designs this catalytic converter with integrated exhaust manifold to match original equipment specifications on the listed vehicles for reliable replacement performance. It is not CARB certified and is not CARB compliant.
