Product Details

The Flowmaster 717894 FlowFX Cat-Back Exhaust System is engineered for 2019-2026 GM Silverado and Sierra 1500 trucks with 5.3L engines and factory dual exhaust. This bolt-on system features durable 409 stainless steel construction throughout with a 3.00-inch inlet pipe leading to a single inlet/dual outlet Flow FX straight-through muffler for a deep, moderately aggressive sound and maximum performance.

Performance Gains:

  • Maximum dyno-tested gains of 21 hp and 26 lb-ft of torque at the rear wheels
  • Straight-through muffler design maximizes exhaust flow
  • Mandrel-bent tubing eliminates flow restrictions

Premium Construction Features:

  • Dual 2.50-inch mandrel bent tailpipes custom routed to clear the factory spare tire and tow hitch without clearance issues
  • Exits through factory exhaust bezels in the bumper, maintaining OEM dual exhaust appearance
  • 409S stainless steel construction for long-lasting durability and corrosion resistance
  • Utilizes all factory hanger locations for simplified installation

Installation and Warranty:

  • Complete bolt-on system with no cutting or welding required
  • Includes all necessary hardware and detailed installation instructions
  • Easy at-home installation typically completed in 1.5-2 hours
  • Backed by Flowmaster's Lifetime Limited Warranty

This system delivers the signature Flowmaster sound—a deep, powerful tone both inside and outside the vehicle without excessive drone. Perfect for truck enthusiasts seeking enhanced performance and an aggressive exhaust note while maintaining daily drivability.

Fitment Notes: Fits 2019-2026 new body style GM Silverado/Sierra 1500 trucks with 5.3L engine and factory dual exhaust. Compatible with both 2WD and 4WD models. Does not fit Crew Cab 2WD with 2-piece driveshaft or trucks with factory single exhaust system.

Part as described. Priced ok...shipping a little slow.

it was good

Best pricing no hassle

Had to upgrade to a Snell 2010 helmet this year, bought the identical helmet for $200 less than I paid 8 years ago! Fast shipping, I will be checking Autoplicity first in the future!
