Exhaust Question

will a 2.5" Flowmaster American Thunder Catback from a 2000 GT fit a 93 Mustang GT Hatchback???

Yes. You may half to make a few small adjustments to how it attatches to the pipe, but you can get straight or bent pipe for piecing the exaust together from autozone or o'reilly's. I did the same thing when I took one of Mike's flowmaster 40's that used to be on his Cobra and put it on my F150.

The tailpipes will not fit after they go over the axles since you have a GT, if it was an LX you would be fine. But you can cut the pipe after it goes over the axle and make dumps.
