Product Details

Dynomax Part Number 19392 is engineered as a premium exhaust system kit for the Jeep Liberty platform. The Ultra Flo Welded muffler uses a straight-through internal path and welded stainless steel construction, while Continuous Roving Fiberglass (CRF) technology helps reduce interior resonance without eliminating the performance tone. This system is built around a single-exhaust, rear-exit layout and is sized for 2.5-inch exhaust routing.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Restricted exhaust flow from a worn or restrictive factory system
• Excess cabin resonance from an aging muffler
• Corrosion-related exhaust replacement needs
• Loss of exhaust tone after factory system wear
• Need for a direct-fit cat-back upgrade on a Jeep Liberty
