I agree with Stevo. If you replace the stock system with a better flowing catback system, you'd be a lot happier with the sound and performance.

One thing to consider is that if you remove too much restriction, you eliminate the required backpressure to maintain low end torque so don't go too big on an exhaust. For your 5.7L HEMI, I suggest no bigger than 3". Also adding a cold air intake and some form of programming (DiabloSport Predator FTW!!!) will really wake up that HEMI.

The dealer or the manufacturer cannot void your warranty if something fails that is not related to your mods. And, in most cases, they have to prove it contributed to the failure of the component.

So, I'd go with a catback exhaust, a CAI and a programmer on your truck.
