Common Issues This Muffler Can Address

Rust or corrosion in the original muffler body
Exhaust noise caused by a damaged or leaking muffler
Replacement needs after failure of a welded OE exhaust assembly
Restoring factory-style exhaust routing on front-mounted applications
Repairing a restricted or deteriorated muffler section

Installation Notes and Tips

Verify the vehicle’s exhaust layout before ordering, since the OE system on these applications was a welded assembly. The listed fitment is for front position use only, and the muffler uses a center inlet and center outlet pipe arrangement. Confirm inlet and outlet diameters against the existing exhaust system to ensure proper alignment during installation.

For best results, inspect adjoining exhaust components before installation and replace worn sections as needed when the original system shows corrosion or weld failure. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

AP Exhaust manufactures replacement exhaust components for direct-fit service applications, and this muffler is built to match the listed vehicle fitment and OE-style sound characteristics. Part number 700484 is intended for the specified Chevrolet Malibu and Pontiac G6 front exhaust applications.

This part fits 27 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
