MagnaFlow Conv DF 99-04 Subaru Forester 2.5L

If you're working on a 1999-2005 Subaru Impreza, Forester, or 2004 Outback and need to replace the catalytic converter, this Magnaflow unit is a solid option. It's designed to keep your check engine light off and meet strict California Air Resource Board (CARB) emissions standards, making it legal for use in California and other restricted states. Magnaflow uses advanced 3D scanning during their research and development to ensure this converter fits and functions just like the original equipment.

This converter features free-flowing, mandrel-bent tubing that helps maintain exhaust flow for optimal performance and fuel economy. The construction uses highly corrosion-resistant stainless steel, specifically 16-gauge 409 stainless steel tubing for durability and a long service life, along with 308 stainless steel MIG welds. The design also incorporates a compact, low-mass build for better thermal efficiency. Because it's a direct-fit unit, installation is straightforward with the proper tools, as no cutting or welding is required. Magnaflow includes a flange gasket, a donut gasket, and an O2 port plug to help ensure a leak-free seal.

This Magnaflow catalytic converter interchanges with several original equipment part numbers, including 44139FA010, 44139FA160, 44139FA161, 44139SA000, and 44139SA010. It's a well-built replacement designed to meet or exceed OEM requirements for emissions control.
