Flowmaster 817658 American Thunder Cat-back Exhaust System

sounds great! quiet inside the cab

I just installed this kit on my 2022 300s with the Hemi and let me tell you, this car sounds amazing. Install was pretty straightforward and was done in my garage by myself. Another person would definitely been helpful, but I managed. As others have said, the hardest part was removing the stock system. Once that was completed, installing the Flowmaster was a breeze. Sound is deep and mellow and I didn’t sense any drone. Definitely worth the money and time to have that Hemi growl. If you are still in the fence about purchasing, pull the trigger and get it, you won’t be disappointed!

Fits my 2016 Dodge Charger R/T well. Not perfect mind you. The cross bars by the original mid mufflers needed to be lowered on reinstall to clear the new exhaust. This was not hard by any sense of the word, just a matter of placing a spacer (8 spare nuts) before reinstalling the cross bars. This exhaust is aggressive in its sound. Was louder than I thought it would be at first. But after a couple of weeks, not that bad. It sounds great at idle and when you put your foot down. When your engine goes into four cylinder mode, it does have a weird drone noise to it which is why it gets 4 stars and not 5. Would purchase again.

Now my Charger sounds like an American muscle car. American Thunder has the throatty sound a V8 should make and sounds awesome when I romp on the throttle. Flowmaster knocked it out of the park with this exhaust. Not too pricey and the right tone for an everyday street car.

Absolutely Amazing! Installed on a 2016 Charger R/T and couldn't be more pleased. Slight drone at 2000 rpm. But not an issue. Spacers needed for under-body brackets to allow for clearance. Overall, you will not be disappointed with this product; and purchasing the kit on Amazon will save you a $100.00+ from the competition. Enjoy!!

Great exhaust sound everything works the way it’s supposed to I didn’t have to space anything seller took a long time to ship

This exhaust was easy to install, but the clamps are crap. I preferred to have it welded, so I took it to a local shop since it is stainless. 80 bucks later the exhaust was PERFECT.

As pictured. Aggressive sounding mufflers. Increased highway mileage by two mpg. Fit 2015 ChargerR/T perfectly. Less than two hours to install. Including lifting car and removing stock exhaust.
