From all the reading I did before going with LTH's, all I saw was that shorty headers don't provide much in terms of gains as the stock headers are pretty good. It's the cats that are the big restriction on the our Z's. If LTH's are definitely out then I'd just go with some test pipes and a FI CBE. Just give Tony at FI a call and let him know what you're goals are and he'll lay out what your options are.
