Flowmaster (717778): FlowFX Cat-Back Exhaust System for 2017 Charger R/T

The 717778 FlowFX cat-back exhaust system for 2017 Dodge Charger R/T with 5.6 V8 Hemi produces an aggressive exterior and interior sound level with all of the performance benefits you expect from Flowmaster. New features include bright 409S stainless steel tubing; a pair of Flowmaster’s new FlowFX straight-through mufflers with a large 3.00 inch core for maximum performance; and a deep, aggressive sound.

Flowmaster’s system uses a 3.00 inch Scavenger X-pipe cross-over and mandrel-bent tubing for maximum performance. It’s then finished off with 3.00 inch stainless steel tips that exit within the factory exhaust tips in the rear bumper valance. The two-piece tailpipes are designed to reuse the factory exhaust valves.
