As of right now, my truck is bone stock, I ordered a DP for it last night and Im ordering the rest of the kit today. The DP is 3" and at the bottom of that I am going to 4". The only gauge I have on my truck now is a Tranny temp gauge, I know alot of people make it seem as though you have to run a pyro if you make any mods, but this exhaust cant do anything but lower the EGTs anyway, right?? My theory is that I have been runnin without a pyro and this can only make it better, so do I really need one?? Also plan to open up the intake shortly.Thanks a lot,
Andrew
