The Flowmaster® FlowFX® Cat-Back Exhaust System is designed for 2025–2026 RAM 1500 trucks with the 3.0-liter Standard and High Output engines. This true dual exhaust system enhances your truck’s personality while delivering outstanding performance and tone. Manufactured from durable 409 stainless steel, the system features dual 3.00-inch mandrel-bent tubing flowing into a custom-tuned FlowFX series “straight-through” muffler for maximum exhaust flow and a deep, aggressive-to-moderate sound.

Included is Flowmaster’s exclusive Scavenger X-Pipe with D-Port technology, increasing exhaust pulse velocity and improving both sound and performance. The dual 3.0-inch tailpipes exit through factory bumper cutouts with 4.5-inch black ceramic-coated tips, and tuned resonators help maintain a quiet interior. Standard Output models are converted to a true dual system, matching High Output and RHO configurations for future performance upgrades. Dyno-tested gains on High Output models reach +26 hp and +23 lb-ft at the rear wheels. The system installs easily using all factory hanger locations and includes all necessary hardware and instructions. Backed by Flowmaster’s Lifetime Limited Warranty.
