Description

The Steeda 555-3622 is a 3-inch diameter cat-back exhaust system engineered to deliver a deep, aggressive muscle car tone for the 2018+ Ford Mustang GT (S550 chassis). Constructed from premium 304-stainless steel, this system offers superior corrosion resistance compared to other materials. The oversized 3-inch tubing diameter is optimized for maximum horsepower and airflow, ensuring that your exhaust system does not restrict performance, whether you have basic bolt-ons or full-on power adders. It integrates seamlessly with most long tube headers and includes necked-down adaptors for a direct fit to factory catalytic converters, simplifying installation. Installation is straightforward, typically taking 2-3 hours with common hand tools, making it a viable DIY upgrade. It is finished with striking 4-inch diameter quad chrome tips.
