Your truck has the MDS . I've heard alot of people talk about the way these trucks sound like once you change out the exhaust . Hopefully someone will give you some advice on what to do and what not to do . Your ultimate choice , if your not to worried about gas mileage would be to turn off the MDS with your Predator then you could do whatever you want . I'm not sure if your tailpipes have resonators in them . But that too is another option you can play with . Remove them or or leave them alone . I myself like the sound of the chambered exhaust . Heres a clip with a Jeep SRT8 with chambered mufflers .
. Good luck with whatever choice you make . Let us know what you've done . Talk to ya soon . Come home safe . Tom
