Flowmaster 718100 Flow FX Cat-Back Exhaust System Ford F-250/F-350 17-26

Flowmaster Flow FX Cat-Back Exhaust System

The Flowmaster Flow FX cat-back exhaust system is designed for Ford F-250 and F-350 Super Duty trucks equipped with 6.2L, 6.8L, or 7.3L engines. Constructed entirely from durable 409 stainless steel, the system features 3.50-inch to dual 3.00-inch mandrel-bent, 16-gauge tubing to improve exhaust gas flow and long-term durability.

A Flowmaster Flow FX straight-through performance muffler delivers a deep, aggressive-to-moderate exhaust tone while supporting maximum performance. Dyno testing showed gains of up to 11 horsepower and 15 lb-ft of torque at the rear wheels compared with the stock exhaust.

The exhaust exits on both sides behind the rear wheels and includes 4.50-inch black ceramic-coated tips for a custom appearance. The system uses the existing factory hanger locations and includes factory-style hangers, complete installation hardware, and installation instructions.
