Tons of options brotha. Lots of good vendors on here. I have had lots of luck dealing with No Limit. But you basic package will consist of these things no matter who you deal with.
1. 4 or 5 inch downpipe back exhaust/*** deleete
2. Egr deleete or egr blockoff plates
3. Tuner (SCT, H&S, *******, Ezlynk) with custom tunes.
4. Intake (the 2 favorites by far are No Limit or Absolute Performance)
Like I said man there are many great vendors however I have always went with No Limit and they have always made me happy
Goodluck
