Flowmaster 717869 Flow FX Cat-Back Exhaust System Chevrolet Silverado/GMC Sierra 1500 14-19

Flowmaster Flow FX Cat-Back Exhaust System

The Flowmaster Flow FX cat-back exhaust system is constructed from durable 409 stainless steel and features a 3.00-inch inlet pipe connected to a single-inlet, dual-outlet Flow FX straight-through performance muffler. The system delivers a deep, powerful tone and maximum performance.

Dual 2.50-inch mandrel-bent tailpipes exit at an angle behind the rear wheels, directing exhaust away from a boat or travel trailer while towing. The system includes two large 4.50-inch black ceramic-coated 304S stainless steel exhaust tips for a custom appearance.

The exhaust system uses the existing factory hanger locations and includes an additional hanger for installing the new left-side tailpipe. Installation instructions and all necessary hardware are included for convenient at-home installation.
