I'm going to be installing a few parts next week on my '01 gt and was wondering if there is anything to watch out for. The parts are; bbk l/t, d&d 3650, fidanza clutch, accufab tb & plenum and a few others. I already have o2 extensions and I'll be replacing all of the o2's and also a new set of plugs. Any recomondations on which brand is best? Any help appreciated.
