Ford Fiesta ST Thermal R&D Exhaust Install | Step-by-Step + Sound Test

Where to buy: https://thermalrd.com/?sca_ref=122384... In this video, I install a Thermal R&D cat-back exhaust on my Ford Fiesta ST. This step-by-step installation covers the complete process, tools, fitment, and tips, followed by a drive and exhaust sound test so you can hear how it sounds on the road. The Thermal R&D Fiesta ST exhaust features a 3-inch design, high-quality construction, and True Helmholtz Technology designed to reduce unwanted drone while delivering a more aggressive exhaust note. ‪@thermalrd‬ #fordfiestast #fiestast #fordfiesta #thermalexhaust #thermalrd #exhuastinstall #exhuastsound #autodiy
