Product Details

Walker Part Number 28014 is a reflection-type muffler with a 23-inch body length, 11-inch body width, and 5.5-inch body height. The aluminized steel body and aluminized finish are selected to resist corrosion better than low-carbon steel, while the direct-fit layout helps maintain the original exhaust routing on 2003-2007 Infiniti G35 and 2003-2006 Nissan 350Z models. This part cross-references Carlson 7544 for the same application.

Common Exhaust Issues It Can Address

• Excessive exhaust noise from a worn or damaged muffler
• Rust-through or corrosion on the original muffler body
• Broken internal muffler components causing poor sound control
• Fitment problems from a previous non-OE-style exhaust repair
• Reduced exhaust appearance from a deteriorated rear muffler assembly

Installation Notes and Tips

Fits 2003-2007 Infiniti G35, N/A. Fits 2003-2006 Nissan 350Z, N/A. Verify inlet and outlet orientation, flange style, and exhaust routing before installation.
