Designed to Optimize OEM Valance Thermal R&D Exhausts True Helmholtz Technology The Ford Focus ST demanded a true 3” diameter exhaust for peak performance. The system also demanded our True Helmholtz Technology to attack the drone that would inevitably sneak in if not properly addressed. After including a resonator in the mid-pipe, we added an external Helmholtz resonator to cancel specific frequencies – namely drone at cruising speeds. We rounded out the system with a unique tip that fit the OEM valance perfectly and completed an exhaust package that any ST owner would be proud to run on the street or the track. Thermal R&D Exhaust systems are designed with quality of sound and manufacturing as our number one goal. Built from T304 Stainless Steel, the fit and finish of our products are designed for performance on both the street and the track. Understanding that the exhaust is the starting point for many builds, our high-performance exhaust will allow additional modifications to perform at their peak. We engineer our products with the goal of achieving the best all-around product for a given application.
