The Acura TL typically has two catalytic converters in its exhaust system.
Across its two generations—2004–2008 with the 3.2L V6 and 2009–2014 with the 3.5L V6—the TL commonly uses a dual-cat exhaust layout in most North American models. This means one catalytic converter sits close to the engine (close-coupled), and a second converter is located downstream along the exhaust path. The dual-cat configuration helps meet emissions standards and optimizes exhaust flow for a V6 engine.
Generational overview
The following summarizes the stock configuration for the two main TL generations in the US market.
- 2004–2008 Acura TL (3.2L V6): Two catalytic converters — a close-coupled cat near the manifold and a second cat downstream.
- 2009–2014 Acura TL (3.5L V6): Two catalytic converters — the same general dual-cat arrangement as the earlier generation.
Note: While two catalytic converters are standard on these generations, variations can exist for non-US markets, different trims, or aftermarket exhausts. Always verify the exact layout for your vehicle by checking the VIN or service documentation.
Why a dual-cat setup?
Dual catalytic converters reduce emissions more effectively by treating exhaust gases in two stages and help maintain proper backpressure and engine performance across a V6 engine. They are a common feature in modern Acura V6 models, including the TL.
Maintenance considerations
If a converter fails, technicians typically inspect and may replace both units to ensure balanced performance and emissions compliance. Replacing one cat without the other can lead to uneven exhaust flow and compliance issues.
Summary: In most Acura TL models, there are two catalytic converters in the exhaust system—one near the engine and one downstream—across the 2004–2014 production span. Always confirm the exact setup for your specific year and market.
