Do I need a intake? Or will the stock one be fine? This is my first diesel.
youre stock intake should handle to about 500hp...but if you can get a deal with a complete package then you are better off getting it with that.
S&B intake seems to be the favored and reliable intake followed by AFE.
exhaust...well its mainly straight pipe from the down pipe back. muffler is optional...
flo pro is an inexpensive set up and does the job the way its supposed to! there is also the afe exhaust, which is a nice set up and MBRP is also very nice!
spartan is a nice tuner to have and has an awesome display screen on which to monitor your parameters with a wide variety of gauges.
SCT is a VERY good tuner and not as expensive but is very capable of big power...especially if you get tunes from eric from innovative.
H&S is also very good with a on the fly tuner which is always a plus!!! they dont use the sensors in the dpf or cat so there is need for welded bungs.
