Description
Overview
The Flowmaster Flow FX Direct-Fit Exhaust Muffler Assembly is a value-packed performance upgrade engineered for the 2014-2026 RAM 2500/3500 trucks equipped with the 6.4L HEMI engine. Designed as a true direct-fit muffler, this Flowmaster exhaust replaces your restrictive factory muffler and helps you customize your RAM truck to your personality with a bolder tone and improved performance. If you’re ready to shop for exhaust upgrades that deliver real results, this Flow FX system is built to perform for the long haul.
At the heart of this exhaust system is a 409 stainless steel Flow FX series “straight-through” muffler, an absorption-style design that produces great sound and maximum performance without unwanted drone. A 3.50-inch inlet pipe feeds the muffler, which then connects to the factory tailpipe for a simple and effective performance upgrade. The entire assembly — body, pipe, and muffler — is constructed from 409 stainless steel for years of trouble-free service.
Key Benefits
This performance exhaust is dyno-proven to deliver max gains of 13 hp and 11 lb-ft at the rear wheels, translating to better acceleration and improved towing performance. With a moderate sound level, you get an aggressive yet livable tone that sounds great without droning on the highway. Whether you drive a 2WD or 4WD model, this cat back muffler system fits both configurations.
