Detailed Description

Walker 47721 is a resonator and pipe assembly for the Acura Integra exhaust system, built to follow original equipment dimensions and connection style. The aluminized steel finish helps provide durable corrosion resistance, while the round 17-inch resonator body is tuned to support OE-style exhaust tone and steady flow. This part cross-references MAHLE 54038 for the same application.

For drivers searching for a 1994-2001 Acura Integra exhaust resonator and pipe assembly, Walker 47721 offers a direct-fit replacement format with welded flange ends and a long overall assembly length of 72.75 inches. The design supports factory-style exhaust routing on Acura Integra models and is a practical choice when replacing a worn or damaged resonator section.

What It Helps Address

  • Exhaust noise from a worn resonator section
  • Rust or corrosion in the original pipe assembly
  • Damaged flange connections at the exhaust joint
  • Reduced exhaust flow from a restricted assembly
  • Fitment issues when replacing the factory-style resonator and pipe

Installation Notes and Tips

Verify the vehicle is a 1994-2001 Acura Integra before ordering, and compare the inlet and outlet flange style to the original assembly. Because this part uses welded flanges and a long pipe assembly, careful alignment during installation is important to maintain proper exhaust routing and sealing. Confirm clearance around the exhaust path before final tightening.

Quality Assurance

Walker designs this resonator to fit, perform, and sound like the original system, using tuning methods aimed at OE-style exhaust characteristics. Part number 47721 is built as a replacement-grade exhaust component for Acura Integra applications.
