Flowmaster Outlaw Muffler for 2014 Ram
Wow, just wow... It exceeded my expectations. Installation was easy as long as you use penetrating oil to loosen the existing mounts. Install took around an hour, and the sound is amazing. It isn't so loud your neighbors will complain, but it does have a nice throaty roar.

This exhaust is so bad I don't even know where to start. But to start my truck has a kn 63 CAI. Which is awesome.. The exhaust killed my mpg and power. Feels like it may have a bit more on top of RPM band but from low to mid is terrible. The truck has to stay in gears for longer bc it lost the low end torque. Sound is awful. It sounds like a v6 and IMHO is not good. There is not a lot of difference between a rice rocket and my truck. It is loud tho. Overall I'd pass on exhaust or get the 3".
