Good choice first of all, i have that on my car and it sound awsome and i just have the stock H pipe.
Borla doesnt have this system for the 97 GT.
its only for
99-03 4.6L RWD AT/MT 2dr. Model # 140067 Tip Style 3, Split rear
I dont know if anyone has tried instaling one but id guess it would need some modification.
