Walker 47821 Exhaust Resonator and Pipe Assembly
Walker 47821 is an exhaust resonator and pipe assembly built for OE-style fit, sound, and flow. It is a direct replacement for select Saturn Vue models from 2004-2007 and uses aluminized steel construction for everyday exhaust service.
For Saturn Vue exhaust repair, Walker 47821 combines a tuned resonator section with a pipe assembly to match original system characteristics. The design supports factory-like exhaust tone while maintaining the correct routing and connection style for the application.

Installation Notes and Tips
Verify the inlet flange style, outlet connection, and overall length before installation.
