Introducing Flowmaster's new FlowFX® Cat-back exhaust system for the 2015-2020 Dodge Challenger models, including Hellcat, with the 6.2L or 6.4L Hemi engine and Factory Active Exhaust Valves. This system is perfect for the person looking for a moderately aggressive exterior and interior sound level with all of the performance benefits that you would expect from Flowmaster®. Features include mandrel bent 3.00 in. stainless steel tubing into the Scavenger Series® X-pipe cross-over for maximum performance and tone, flowing into a pair our new FlowFX straight-through mufflers for a deep and powerful sound. The dual 3.00 in. mandrel bent stainless tailpipes retain the Factory Active Exhaust Valves and the system is finished off with aggressive looking quad 3.50 in. black ceramic coated 304s stainless steel tips embossed with the Flowmaster name, putting everyone on notice that you would rather lead than follow. The large quad tips exit within the rear bumper valance and gives your car the look that it should have come with from the factory. This system is designed to use the factory hanger locations, includes all necessary parts, hardware and detailed instructions for a relatively easy at home installation.
