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. Because this is a specific-fit muffler, matching the vehicle’s original configuration is important for proper alignment and sealing. Professional exhaust installation is recommended when replacing a welded or flange-connected muffler assembly.
Quality Assurance
