Description
Overview
The Flowmaster Signature Series cat-back exhaust system is engineered specifically for the 2021-2026 Ford F-150 equipped with the 2.7L, 3.5L, and 5.0-liter engines, as well as the PowerBoost 3.5L, when fitted with the optional factory dual exhaust exiting the rear bumper. This complete performance exhaust system delivers a deep, throaty note with aggressive-to-moderate sound levels both inside the cab and outside the truck, all while unlocking the flow and performance benefits you expect from a genuine Flowmaster exhaust system.
Every component is built from mandrel-bent 304 stainless steel 3.00-inch tubing, feeding into a Signature Series straight-through muffler and exiting through large 3.00-inch dual tailpipes for maximum sound and airflow. As a true catback exhaust, it bolts on behind the catalytic converter and routes cleanly through the OEM rear bumper cut-outs, using all the factory hanger locations for a precise, no-cut fit.
Key Benefits
This is more than an exhaust pipe upgrade — it’s a matched exhaust system designed to improve breathing, tone, and appearance in one bolt-on package. The straight-through Signature Series muffler produces that signature Flowmaster growl, while the dual 3.00-inch pipes keep exhaust gases moving. The tailpipes are finished with a pair of large 4.50-inch black PVD stainless-steel tips that give your F-150 a far more aggressive look than the factory tips.
