Description

Controls vehicle emissions with the Magnaflow 19-21 Nissan Altima 2.5L Single Underbody Direct Fit Converter, keeping the check engine light off while maintaining EPA-compliant emissions control.

This Magnaflow OEM-grade, federal/EPA compliant direct-fit catalytic converter (part 280387) is engineered for reliable emissions performance and straightforward replacement on compatible Altima models. Designed by Magnaflow, a recognized name in performance exhaust components, the unit balances durability and flow characteristics appropriate for direct-fit service items.

  • OEM Grade Federal/EPA Compliant Direct-Fit (280387) — Ensures emissions control meets federal standards and fits the original underbody mounting points, reducing installation time and avoiding modification to the exhaust system.
  • Free-flowing mandrel-bent tubing — Promotes smoother exhaust flow through the converter body; this high-flow geometry helps minimize backpressure compared to restrictive bends, supporting consistent engine operation and compatibility with performance exhaust upgrades.
  • Highly corrosion-resistant stainless steel construction — Provides long-term resistance to rust and road corrosion, extending service life in underbody conditions and maintaining structural integrity under thermal cycling.
  • Spun body converter — Delivers a uniform, durable shell around the catalytic substrate for consistent sealing and protection of the catalyst material during normal use.
  • Direct-fit design with user-friendly installation — Configured for straightforward replacement; the direct-fit nature allows many technicians and experienced DIY installers to install the converter without extensive exhaust modification.

Technical focus: this converter is intended as a direct replacement component to restore required emissions control while offering free-flowing characteristics suited for performance exhaust contexts and turbo upgrade compatibility where original fitment is retained.
