MagnaFlow Header with Catalytic Converters - 2014-2023 Subaru 2.0L & 2.5L Engines

Let’s face it, when your factory header and catalytic converter start going south, you know it. The check engine light shows up like an unwelcome house guest, and the smog station gives you that look. Chances are, you’ve got a "catalyst below efficiency" code pointing straight at the primary catalytic converter.

If you’re really "lucky," that blown-out front cat has sent debris downstream, clogging the secondary cat and choking the life out of your car. Sluggish throttle response, lack of power, maybe even a lovely little exhaust leak from the header or the front pipe flange? Yeah—those are all classic signs.

Sure, the dealer might tell you to "try some catalytic converter cleaner" like it’s a miracle cure. Spoiler alert! No amount of snake oil is fixing a blown out cat.

That’s where this MagnaFlow OEM Grade Header with Integrated Catalytic Converter comes in.

This direct-fit replacement is built to meet or exceed federal emissions standards, and it bolts right up like it belongs there. No weird fitment games. No surprise fabrication projects. Just solid construction and proper flow.

Why We Like It:

• Direct-Fit: Designed to bolt up to your factory exhaust system with OEM-style flanges and hangers.
• Federal EPA Compliant: Meets emissions standards for Federal applications. (Not legal for sale in California, Colorado or New York.)
• Better Flow: Helps restore lost performance from a clogged or failed cat.
• OEM Fitment at a more affordable price point.
• Stainless Steel Construction: Engineered for longevity and reliable emissions performance.

If your old header’s cracked, your cat’s toast, and you’re tired of failing emissions, this is the clean, bolt-on solution to get your Subaru breathing right again.
