Detailed Description

Walker 55572 is engineered for 2007-2012 Nissan Sentra exhaust service where an OE-style resonator and pipe assembly is required. The resonator is tuned to support original-system sound characteristics while maintaining flow through a steel construction and aluminized exterior finish. With a 25-inch round body and 60-inch overall length, this assembly is built around the factory-style layout used on Sentra models with Federal Emission System and California Emission System configurations.

For buyers searching for a Nissan Sentra resonator pipe, Walker 55572 provides a direct-fit replacement path for restoring exhaust routing and resonator function without changing the vehicle’s original exhaust character. The 2-bolt welded flange inlet and outlet help match the factory connection style on the listed applications.

What It Helps Address

• Exhaust resonance or drone from a worn resonator
• Rust damage in the resonator or pipe section
• Leaks at the resonator-to-pipe connection points
• Factory exhaust tone that has become louder or uneven
• Replacement needs on 2007-2012 Nissan Sentra exhaust systems

Installation Notes and Tips

Verify the vehicle’s emission system before ordering: this Walker 55572 assembly is listed for 2007-2012 Nissan Sentra models with Federal Emission System and California Emission System. Confirm flange style, overall length, and routing against the original exhaust assembly before installation. Professional exhaust installation is recommended to ensure proper alignment and sealing at the welded flange connections.

Quality Assurance

Walker designs this resonator assembly to follow original-system fit, performance, and sound targets using precise tuning methods for OE-style exhaust behavior. The part number 55572 is also referenced by BRExhaust 284-659 for the same application.
