Flowmaster's® Flow FX Direct-Fit Muffler exhaust system for the 2014-2025 RAM 2500/3500 trucks with the 6.4L HEMI engine gives you a great value packed way to help you customize your RAM truck to your personality. This performance muffler system fits both 2/4 Wheel drive models and is manufactured from 409 stainless steel for years of trouble-free service and performance. Features include a 3.50-inch inlet pipe leading into a 409 stainless steel Flow FX series "straight-through" muffler for great sound and maximum performance and no drone. The muffler then connects to the factory tailpipe for a simple and effective performance upgrade. Max dyno gains of 13 hp and 11 lb-ft at the rear wheels. This results in better acceleration and towing performance. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Kits include installation instructions and all necessary hardware. Backed by Flowmaster's Lifetime Limited Warranty.

Features:

  • 3.5-inch mandrel bent 16-gauge 409 stainless steel tubing maximizes exhaust flow and improves durability
  • Kit includes complete hardware and factory styled hangers in the stock locations for an easy installation
  • A tuned Flow FX style muffler delivers a deep, aggressive to moderate performance tone and improves exhaust flow with no drone
  • Max increases of up to 13 hp and 11 lb-ft over the stock exhaust at the wheels
  • Tuned performance muffler eliminates interior drone
  • Maintains factory warranty
  • Lifetime Limited Warranty
