Product Details

As part of the Bosal BRExhaust Direct-Fit Exhaust line, this muffler assembly focuses on OE-style replacement fitment and consistent exhaust routing for import and domestic vehicles. The BRExhaust direct-fit design is intended to match factory mounting points and exhaust geometry, making it a practical choice for replacing a worn front silencer on a 2001-2004 Nissan Pathfinder or a 2001-2003 INFINITI QX4. The flanged inlet and outlet, dual inlet configuration, and single outlet layout support a direct replacement installation path. Part number 283-713 is engineered to reduce exhaust noise while maintaining low backpressure.

Common Reasons to Replace

• Exhaust noise from a worn or rusted front muffler assembly
• Corrosion damage to the original aluminized exhaust components
• Loss of factory-like exhaust tone
• Restricted exhaust flow from internal deterioration
• Fitment issues with a damaged or non-original exhaust section

Installation Notes

This muffler assembly uses a direct-fit, bolt-on configuration for the listed vehicles. Confirm front-position fitment before installation and verify flange alignment with the existing exhaust system. Because the assembly is designed around OE-style mounting and pipe routing, it is suited to replacement of the front silencer section on the specified Pathfinder and QX4 applications.
