Flowmaster's® Signature Series Cat-back exhaust system is designed specifically for the 2019-2024, 2026 RAM truck (new body) with 5.7L Hemi and factory dual exhaust. Features include full brushed 304 stainless steel construction, large 3.00-inch flanged inlet pipe flowing in the single inlet/dual outlet Signature Series "straight-through" muffler for great sound and maximum performance. This premium exhaust system is TIG welded for a stronger, more precise weld that looks as good as this system sounds. The dual 2.50-inch mandrel bent tailpipes clear the factory hitch and spare tire and exit out through the factory rear bumper cutouts with large 4.50-inch diameter PVD coated black chrome 304S stainless steel tips giving your RAM that custom look that goes hand in hand with that deep performance Signature Series sound. Max dyno gains of 13 hp and 13 lb-ft at the rear wheels. The system uses all the factory hanger locations and connections for an easy installation that you can do at home. Includes installation instructions and all necessary hardware. Note: This system fits all wheelbases, both two and four wheel drive models along with all cab and bed configurations.

Features:

  • • Brushed 304 stainless steel offers maximum corrosion resistance for a cleaner and more high-end appearance.
  • • TIG welding offers a more precise weld, better heat control and high-end appearance compared to MIG welding.
  • • Black chrome tips offer a stylish upscale look.
  • • Signature Series muffler offers an aggressive to moderate performance tone and increased performance over the stock system.
  • • Installer friendly design allows for an at home installation.
  • • Dyno proven performance gains you can feel.
  • • Increased power and torque over the stock exhaust system.
  • • Brushed appearance removes tooling marks for a cleaner overall look.
