Description

SYS 19-26 GM 1500, 5

Introducing our new Flow FX® Cat-back exhaust system for the 2019-2026 GM Silverado/Sierra 1500 with the 5.3L engine. The performance exhaust system fits both 2 and 4-Wheel drive models with 148 or 157-inch wheelbases and is manufactured from 409S stainless steel for years of trouble-free service. Features include a 3.00-inch inlet pipe leading into a Flow FX "straight-through" muffler for great sound and maximum performance. Maximum dyno gains of 10 hp and 12 lb.ft of torque at the rear wheels. The 3.00-inch mandrel-bent tailpipe exits out behind the rear passenger side tire and is finished off with large 4.50-inch diameter black ceramic coated 304S stainless steel tip, giving your Silverado/Sierra that custom look that goes hand in hand with the deep performance sound of the Flow FX muffler. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes detailed instructions and all necessary hardware.

Important Notice relating to US Domestic Market Trucks & Pickups

Many US-market trucks and pickups are available in multiple cab and bed-length configurations (e.g., Single Cab, Extended Cab, Double/Crew Cab, CrewMax, 5.5ft/6.5ft/8ft beds, etc.). Exhaust system fitment can vary between these chassis versions.

Where available, we list all compatible vehicles, cab types, and bed lengths in the product description. However, depending on your exact configuration, some systems may require optional extension/mid-pipes or minor modification for correct fitment.

Because of these variations, please carefully check your cab configuration and bed length before purchasing. If you are unsure, or if your vehicle has been modified, please reach out to a StreetFX agent.
