Product Details

Magnaflow is well-known for making exhaust components that flow well and sound great. For your 2006-2007 Subaru Impreza 2.5L, this direct-fit catalytic converter is designed to keep your emissions system in check and your check engine light off. It's built to meet or exceed California Air Resource Board (CARB) requirements, meaning it's legal for use in California and other states with strict emissions standards.

This converter is made with free-flowing, mandrel-bent tubing to help maintain smooth exhaust flow, which is important for both performance and fuel efficiency. The construction uses highly corrosion-resistant stainless steel, so it's built to last. Magnaflow uses advanced 3D scanning during their design process to ensure this converter fits just like the original equipment, making installation straightforward. The single laser fusion weld is designed to prevent leaks, and its compact, low-mass design helps with thermal efficiency.

Installation is intended to be a DIY job with the right tools, as no cutting or welding is needed. It comes with the necessary flange gasket, donut gasket, bolt, and flat washer to help you get a proper seal. This converter interchanges with several original equipment part numbers, including 44101FE040 and 44611AA130.
