Detailed Description

The Bosal BRExhaust Federal Direct-Fit Premium Load OBDII Exhaust Manifold with Integrated Catalytic Converter is built as a replacement for the left-side exhaust position on select Toyota trucks and SUVs. The stainless steel body helps resist corrosion, while the ceramic substrate supports emissions conversion in a direct-fit assembly that matches the original-style layout. Part number 096-1668 is a practical choice for restoring exhaust system function on 2003-2011 Toyota 4Runner, 2005-2010 Toyota Tacoma, 2007-2009 Toyota FJ Cruiser, and 2005-2006 Toyota Tundra applications listed for this configuration.

The BRExhaust Premium Load line focuses on direct replacement fitment and emissions compliance for Federal/EPA-regulated vehicles. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Check engine light concerns related to catalytic converter efficiency
• Failed emissions inspection results
• Corrosion or cracking in the original manifold/catalyst assembly
• Restricted exhaust flow from a worn converter
• Noise or exhaust leakage from a damaged manifold assembly

Installation Notes and Tips

Fits 2005-2010 Toyota Tacoma, left. Fits 2011 Toyota Tacoma, left, split date to 9/1/2011. Fits 2003-2009 Toyota 4Runner, left. Fits 2007-2009 Toyota FJ Cruiser, left. Fits 2005-2006 Toyota Tundra, left.

Direct-fit construction supports a bolt-on installation with no cutting, welding, or fabrication required. Verify the vehicle’s left-side application, OBDII configuration, and emissions requirements before installation. Use the included gasket and mounting hardware during replacement, and confirm sensor placement matches the pre-converter oxygen sensor location.

Quality Assurance

Built by Bosal under the BRExhaust Premium Load line, this converter uses stainless steel construction and a ceramic substrate to support long service life and reliable emissions performance in Federal/EPA-compliant applications.
