What It Helps Address

• Exhaust drone or resonance after the original resonator wears out
• Rust-related failure in the resonator or pipe section
• Loss of factory exhaust tone on Lexus GX460 and Toyota 4Runner models
• Damaged or leaking exhaust connection at the flange or outlet area
• Reduced exhaust flow caused by a deteriorated resonator assembly

Installation Notes and Tips

Verify inlet and outlet orientation, overall length, and flange style before installation. This Walker 54611 assembly uses a 2-bolt welded flange inlet and spout outlet, so matching the existing exhaust routing is important for proper alignment.
