Catalytic Converter for Acura TSX (2009-2014) 2.4L

Direct-Fit Catalytic Converter for 2009-2014 Acura TSX

Direct Bolt-On Emissions Replacement: Replaces degraded factory catalytic converters to eliminate P0420 diagnostic trouble codes and restore proper exhaust scavenging on 2.4L K-series applications.

The Stock TSX Catalyst Degradation

Over extended mileage, the factory catalytic washcoat on high-revving K24 engines suffers thermal fatigue and precious metal depletion, resulting in catalyst efficiency failure and persistent check engine lights. Internal matrix breakdown or partial clogging increases exhaust backpressure, restricting cylinder evacuation at higher RPMs and degrading both fuel economy and throttle response.

The Engineering Solution

Built with a durable stainless steel outer body and mandrel-bent aluminized tubing, this unit resists structural corrosion and high thermal cycling. Precision OE-style flanges align directly with factory mounting points and downstream exhaust sections for a true bolt-on fitment without welding or pipe cutting. The high-efficiency internal monolith provides optimal emissions conversion to satisfy Federal EPA parameters while preserving unimpeded exhaust flow.
