Detailed Description

Dynomax Super Turbo Universal, part number 17673, is an oval exhaust muffler engineered with large internal flow tubes to improve exhaust flow while reducing backpressure. The fiberglass matting helps absorb unwanted resonance, which supports a smoother sound profile without eliminating performance character. Its aluminized steel construction and reversible layout make it a practical choice for custom exhaust fabrication and direct replacement work where a universal muffler is required. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Compatible With Chevrolet Silverado 1500, GMC Sierra 1500, Ford F-150, Dodge Ram 1500, and other listed applications when the vehicle-specific exhaust notes match the fitment data. The 17673 is also listed for Chevrolet Silverado 1500 HD, GMC Sierra 1500 HD, Ford Expedition, Lincoln Navigator, Cadillac Escalade, Chevrolet Tahoe, GMC Yukon, Dodge Durango, Dodge Ram 2500, Dodge Ram 3500, Ford F-250, and Ford F-150 Heritage in the specified years and configurations.

Installation Notes and Tips
