About this product

Part #: 817658

Flowmaster's American Thunder Cat-back exhaust system for the 2015-2016 Dodge Charger R/T with the 5.7L V8 engine and 2015-2018 Chrysler 300 with 5.7L V8 engine is perfect for the person looking for an aggressive exterior and interior sound level with all of the performance benefits that you would expect from Flowmaster. This bolt-on 409S stainless steel system features a pair of Super 44 Series mufflers for a deep, aggressive sound. The system uses a 2.50 inch Scavenger Series X-Pipe and mandrel bent tubing for maximum performance and then is finished off with 2.50 inch stainless steel tips that exit within the rear bumper valence. The exhaust system is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.

What made you choose this particular product?

it was a gift for high school graduation from my uncle, i've been wanting a flowmaster for quite some time, so finally having one made me happy.

Is this your first time buying from this brand? Did you consider other brands?

yes, having never put an exhaust on any car that i or my family has owned, flowmaster had the best sound to make my 4.0 more noisy without being obnoxious

Was it easy to install? Any installation tips that will help others?

did require cutting and welding

What made you choose this particular product?

Super 40'soft sound amazing...but drone makes them not family or neighbour friendly.

Is this your first time buying from this brand? Did you consider other brands?

Yes. I have used magna flow in the past, better for longer drives but not as nasty sounding...and I mean nasty in a good way!
