The Flo Pro Exhaust Twister Diesel Race Resonator is engineered to deliver maximum exhaust flow while reducing unwanted exhaust noise and cab drone. Featuring an innovative corkscrew spiral baffle design, the Twister creates a dual flow path that helps equalize exhaust pulses, minimize turbulence, and accelerate exhaust flow for improved performance. Unlike traditional resonators, the spiral core design is less restrictive, allowing your diesel engine to maintain strong horsepower and throttle response while producing a cleaner, more refined exhaust tone. Constructed from fully welded steel for long lasting durability, the Twister Race Resonator is built to withstand the demands of daily driving, towing, and high performance diesel applications. Its compact design makes it ideal for installations where space is limited, and it is an excellent solution for reducing exhaust noise to meet many track requirements without the significant horsepower loss associated with conventional mufflers. The Twister also helps eliminate cab drone in many diesel truck applications, making long drives more comfortable while maintaining the aggressive sound diesel enthusiasts expect. Designed for universal installation, the Flo Pro Twister Diesel Race Resonator is an excellent choice for custom exhaust systems, performance upgrades, street driven trucks, tow rigs, and race applications where maximum flow, reduced restriction, and improved sound quality are the priority.
