If I go E-tune such as the infamous tune will that be good enough to hold me over for a while? I plan on getting protuned at EFI but would like to add some exhaust bits and maybe a couple other things before the final tune.
This should all be done by around October before I drive from NY to CO for the winter. Also I've seen some debate wether or not to go Catted or Catless on the downpipe, I've seen some say that having the cat isn't so good for long trips such as the one I will be making due to the prolonged periods of high heat in the engine bay. Any truth to this?
