i have a 04. 5 6-speed 4x4 and i was wondering what i can do to bom. my truck without boming my warranty. i have 8300 on it now and i placed a thread on here awhile back about running a straight 4'' from the &#%@ CAT. out . also want to put in a cold air induction in but i read on here all the time and it appears that the 04. 5 is limited to what you can do . correct me if i am wrong, please
