Detailed Description

Walker 48331 is engineered as a resonator and pipe assembly for vehicles that use a flanged exhaust connection. The steel body and steel pipe are finished in aluminized coating to support exhaust system replacement needs, while the round resonator section measures 20 inches in length and 3.5 inches in height and width. Walker’s tuning approach is aimed at matching the original exhaust character, making this a practical choice for restoring factory-like exhaust tone and flow on the correct application.

This part cross-references AP Exhaust 78217 for the same application. It is a strong fitment-focused option for Toyota Camry exhaust repair, Lexus ES330 exhaust replacement, and Toyota Solara exhaust service where the original configuration uses welded 2-bolt flanges.
