Description

The Dynomax Ultra Flo Welded Cat-Back Exhaust provides a classic sportster vibe with a renewed sound and vigor for your Mustang. Expertly crafted with clear airflow paths and absorbent fiberglass, it dampens unwanted internal resonance and deepens the tone. Designed for refined airflow and dependable delivery, it withstands road debris impact. The stainless-steel structure minimizes corrosion, preventing early rusting and punctures.
