LT's and the ORY will help out a lot--and it will sound badass too! The only thing is with the fitment. LT's and the ORY are a bitch to work with. If you plan on doing a motor or tranny swap in the future, take the time to have either a ball and socket or the 3 bolt flange welded onto the ends of the headers and ORY so a disconnect is easier. If you do the LT's and the ORY before your tune, you will have a Check Engine Light. The rear 02 sensors won't read correctly and throw the CEL to come on. It isn't anything major--just do the tune pretty soon afterward...
