Flowmaster Outlaw on Challenger is a beast!
Stock Challengers are way too quiet for a muscle car, so I deleted the resonators. The sound without the resonators was a big improvement, but after awhile I wanted more. The Flowmaster Outlaw Catback system was just what I wanted. There's a nice rumble at start up and idle, but when you stomp on the gas it just roars. Installation was straight forward and took about 3 hours for removal and installation. My Dewalt XR impact gun made installation a breeze.
Great value for the performance
The perfect fit for my Challenger 5.7L 2016. The installation was complicated but the fitment was perfect. The sound of the car changed a lot at 4.5 to 5.5k rpms! Not so much at idle. The car now accelares way better! At the track when i shift to second gear the tires will spin like crazy! Which is awesome! I have not been able to take the car to the dyno!! But it feels more powerful!
