Description
The Flowmaster Flow FX Cat-Back Exhaust System is engineered for 2014–2019 GM Silverado 1500 and GMC Sierra 1500 Classic Body trucks equipped with the 4.3L or 5.3L engines. This system is built to fit trucks with 143.5-inch or 153-inch wheelbases, and is compatible with both 2-wheel drive and 4-wheel drive models.
Designed using 409 stainless steel, the system delivers long-lasting durability and a moderate, deep performance tone thanks to its Flow FX straight-through muffler. A 3.00-inch inlet pipe feeds into the muffler, followed by a 3.00-inch mandrel-bent tailpipe that exits behind the passenger-side rear tire. The exhaust is finished with a large 4.50-inch black ceramic coated 304 stainless steel tip, giving the truck a bold custom look.
Installation is simple since the system uses factory hanger locations and includes all necessary hardware. A Lifetime Limited Warranty ensures long-term reliability and confidence in your upgrade.
