Description
Overview
The Flowmaster Flow FX Direct-Fit Exhaust Muffler Assembly is a value-packed performance exhaust upgrade engineered specifically for the 2025–2026 Ram 1500 equipped with the 3.0-liter High Output engine. Designed as a true direct-fit muffler system, it lets you customize your truck’s sound and street presence while pulling real, measurable power out of the factory setup. Whether you’re daily driving or towing, this Flowmaster muffler transforms the stock car exhaust into a purpose-built performance exhaust without complicated modifications.
At the heart of the system is a Flow FX series “straight-through” absorption muffler built entirely from 409 stainless steel. Dual 3.00-inch inlet pipes feed into the oval-bodied muffler, which then splits into a dual outlet that connects to your factory tailpipes. The result is a moderate, refined tone that adds attitude without droning — and because it’s engineered as a cat-back-style bolt-on muffler assembly, installation stays clean and straightforward.
Key Benefits
Every component in this exhaust system is manufactured from durable 409 stainless steel, giving you years of trouble-free service against heat, corrosion, and road abuse. The brushed, natural-finish Flow FX muffler mounts using all factory hanger locations and connections, so there’s no cutting, drilling, or fabrication required. Flowmaster backs the entire system with its Lifetime Limited Warranty, and dyno testing shows max gains of 21 horsepower and 18 lb-ft of torque at the rear wheels — power you can genuinely feel behind the wheel.
