Show original supplier description
The FSWERKS Competition Exhaust system is engineered from 3-inch diameter, mandrel-bent T304 stainless steel tubing, designed to maximize flow and support over 500 horsepower for the Ford Focus ST EcoBoost. This competition-focused system features a straight-through, high-flow design without a muffler, finished with polished dual double-wall 4-inch angle-cut T304 stainless steel tips for an aggressive aesthetic. It is designed as a direct bolt-on replacement, including all necessary clamps, hardware, and instructions for installation. The system is CARB legal and retains all factory emissions equipment. While designed for performance, users should be aware that this 'Competition' version is explicitly stated as being very loud, even louder than their 'Race' system, and is not recommended for street use due to significant drone at highway speeds (70-75mph). Installation may require extra room underneath the vehicle, and care must be taken when tightening clamps to avoid shearing bolts. The FSWERKS Competition Exhaust system is a lightweight alternative to the stock system, weighing approximately 26lbs compared to the OEM ~45lbs. All FSWERKS stainless steel exhaust systems are protected by a 5-year limited warranty.
