Product Details

The Dynomax Ultra Flo Welded line focuses on high-flow exhaust performance with welded stainless construction and an unrestricted internal path. Part number 17233 is engineered to move exhaust efficiently while using CRF material to absorb unwanted resonance, helping maintain a controlled tone under load. With a 3-inch pipe connection, oval body shape, and reversible design, this muffler works well in custom exhaust builds where packaging and flow matter. It is a practical choice for drivers building a performance exhaust on a Chevrolet Silverado 1500, GMC Sierra 1500, or Ford F-150, as well as other listed applications.

What It Helps Address

• Excessive exhaust restriction in performance exhaust systems
• Weak or muted exhaust tone from stock mufflers
• Interior resonance caused by aggressive exhaust setups
• Packaging challenges in universal custom exhaust installations
• Corrosion concerns in steel muffler replacements
