Description

The Flowmaster Flow FX Cat-Back Exhaust System is engineered for drivers who want increased power, improved sound, and long-lasting stainless steel performance on their 2011–2018 Chevrolet Silverado or GMC Sierra 1500 equipped with the 6.2-liter V8 engine. Constructed from durable 409 stainless steel with 3.50-inch mandrel-bent tubing, this system provides smoother exhaust flow and enhanced durability.

A Flow FX straight-through muffler delivers a deep, moderate performance tone while maximizing exhaust flow for improved horsepower and torque. Dyno testing has shown increases of up to 16 horsepower and 16 lb-ft of torque at the rear wheels over stock. The exhaust exits behind the rear passenger-side wheel through an eye-catching 5.00-inch black ceramic-coated stainless steel tip, giving the truck an aggressive custom look.

Designed for easy installation, this system uses factory-style hangers in OEM locations and includes all required clamps and hardware. Backed by Flowmaster’s Lifetime Limited Warranty, it provides exceptional performance, durability, and sound at an excellent value.
