Well the 6.1/6.4 SRT Manifolds won't work with out some Work,
The Passenger side will fit with some simple frame rail notching, Drivers side needs the same, plus some modification to the engine bracket and the relocation of the brake proportional calve I'm not against it, but for now I'm going to order some LX body headers and see if they fit, I'd rather cut up $200 headers than notch the rails.
