Overview

The Flowmaster Force II cat-back exhaust system is constructed from durable 409 stainless steel and designed for the 2009-2014 Ford F-150 models equipped with 4.6L, 5.0L, or 5.4L engines. This system features a chambered muffler with a single inlet and dual outlets, leading to 2.50-inch diameter tailpipes that can be configured for a split rear or split side exit. The system includes two 3.00-inch round tips with a slant cut and rolled edge, finished in polished 304 stainless steel.

Engineered for improved acceleration, passing power, and fuel mileage, the Force II system utilizes mandrel-bent tubing to ensure superior exhaust gas flow. The stainless steel construction provides excellent corrosion resistance. This cat-back system fits 2-wheel and 4-wheel drive models across all wheelbases.
