3-Inch T304 Stainless Steel Cat-Back Exhaust

The Thermal R&D Cat-Back Exhaust System is engineered to enhance the performance and sound of the 2014-2019 Ford Fiesta ST. This cat-back system is constructed from 3-inch diameter T304 stainless steel tubing, ensuring durability and corrosion resistance. It features dual 2.5-inch angle-cut tips with a polished finish, providing a more aggressive and aftermarket aesthetic. To mitigate drone issues often associated with larger diameter tubing, Thermal R&D has incorporated straight-through resonators in both the mid-pipe and the rear section. This design allows for unrestricted flow during acceleration while effectively deflecting unpleasant exhaust tones during cruising speeds. The system aims to provide an improved performance and a louder, more aggressive exhaust note without sacrificing daily drivability. Features include T304 stainless steel construction, direct bolt-on application to the OEM catalytic converter, and compatibility with OEM hangers and valance. The benefits listed are improved performance and a louder, more aggressive exhaust note. This product comes with a limited lifetime warranty from Thermal R&D.
