- Direct-fit OE-style muffler assembly for straightforward exhaust replacement
- Reflection muffler design for controlled exhaust flow

Product Details
The Quiet-Flow SS product line focuses on stainless-steel construction and OE-style fitment for drivers who want a replacement muffler assembly that matches the original exhaust layout more closely than a universal part. Walker 48360 uses a pipe connection inlet and outlet, with a 29-inch body length and 91-inch overall length, making it a practical choice for exhaust service on the 2003-2004 Nissan Frontier. This part cross-references Monroe Shocks & Struts (e.g., 210397681) for the same application.
Common Exhaust Problems It Can Address
- Rust-through or corrosion in the original muffler assembly
- Exhaust noise caused by a damaged internal muffler structure
- Restricted exhaust flow from a deteriorated muffler
- Fitment issues when replacing a welded OE-style assembly
- Need for a direct replacement on a 2003-2004 Nissan Frontier

If the original system is welded, replace all required exhaust components during service to maintain proper alignment and sealing. Walker 48360 is intended for direct-fit exhaust repair on the listed Frontier applications.
