This listing is for Flowmaster FlowFX Cat-Back Exhaust System Fits 14-18 Silverado/Sierra 1500 5.3L

Part Number 717869

Flowmaster built its reputation on a single idea: an exhaust system should deliver real performance gains and a sound the driver actually wants to hear. The company's patented Delta Flow technology uses precisely angled internal chambers to scavenge exhaust gases and cancel unwanted frequencies, producing the deep, aggressive tone Flowmaster is known for without the drone that spoils a long drive. The range spans the well-known Super 40, 40, Super 50 and 10 Series mufflers through to complete mandrel-bent cat-back systems, headers and mufflers built for trucks, muscle cars and daily drivers alike. Every system is designed and tested in the United States and built from aluminized or stainless steel for a long service life.

Our new Flowmaster® Flow FX® cat-back exhaust system is manufactured using durable 409 stainless steel throughout and features a 3.00-inch inlet pipe leading to a single inlet/dual outlet Flow FX "straight-through" muffler for great sound and maximum performance. The dual 2.50-inch mandrel-bent tailpipes exit out the side at an angle behind the rear wheels directing exhaust away from your boat or travel trailer when towing. The system is finished off with a pair of large 4.50-inch diameter black ceramic coated 304S stainless steel tips, giving your truck a custom look that goes hand in hand with that deep performance Flow FX sound. The system uses all the existing factory hanger locations and includes an additional hanger to install the new left side tailpipe. Includes installation instructions and all necessary hardware for an easy installation that you can do at home. Notes: Fits 2/4wd models with 143.5 and 153-inch wheelbases and *2019 Classic body models.
