Description
Overview
The Flowmaster Signature Series Cat-back Exhaust System Kit is engineered specifically for 2021-2026 Ford F-150 trucks equipped with the 2.7, 3.5, or 5.0-liter engines. Built to deliver an aggressive-to-moderate tone alongside real, measurable performance, this catback exhaust replaces the restrictive factory piping with a free-flowing, high-quality upgrade that both looks and sounds the part. If you’ve been searching to shop for exhaust that transforms your F-150, this is a complete, ready-to-install performance exhaust system.
At the heart of the system is a TIG welded 304 stainless steel Signature Series muffler that produces the aggressive to moderate sound level Flowmaster is known for. Paired with 3.00-inch mandrel bent, brushed 304 stainless steel tubing, this exhaust pipe design maximizes exhaust flow and durability while keeping a clean, high-end appearance under the truck.
Key Benefits
Every joint in this exhaust system is TIG welded for stronger, more precise welds that look as good as the system sounds. The mandrel-bent tubing eliminates the flow restrictions of crimped bends, helping unlock the dyno-verified max gains of 13 horsepower and 16 lb-ft of torque at the rear wheels. Finishing the look is a larger 4.50-inch PVD coated black chrome tip for a bold, custom appearance that stands out at the bumper.
