Product Details

Walker 47800 is an exhaust muffler assembly in the Quiet-Flow SS line, engineered as a direct replacement for the factory muffler on select Nissan TITAN trucks. The stainless-steel muffler material and body help resist corrosion better than standard aluminized designs, while the oval, combination-style muffler layout supports OE-style exhaust routing. This part cross-references Walker Exhaust 53477 for the same application.

What This Muffler Helps Address

• Rusted or corroded factory muffler housing
• Exhaust noise from a damaged muffler assembly
• Leak points at worn flange or pipe connections
• Fitment issues from a non-OE replacement exhaust section
• Replacement needs on 2004-2006 Nissan TITAN exhaust systems

Installation Notes

Verify inlet and outlet orientation, flange style, and overall length before installation. This muffler assembly uses an offset configuration with 2.25 in. connections, so the existing exhaust routing should be checked against the vehicle’s original layout. If the welded assembly is being replaced, inspect the related exhaust components and replace all required parts as needed for proper sealing and alignment.

Quality Assurance

Walker Quiet-Flow SS muffler assemblies are built with stainless-steel construction and OE-style fitment for domestic and foreign vehicles. This part is listed for 2004-2006 Nissan TITAN applications and is backed by a limited lifetime warranty.
