My friend's 02 GT's Flowmaster mufflers have holes rusted in them and need replaced. It appears they have 2.5" inlets/outlets and weld was used to make up the difference when they were connected. My 2008 Flowmaster catalog lists a couple of different 2.5" mufflers as replacements but the pipe looks to be 2.25". Not concerned with performance. My friend justs wants the sound as she is on a tight budget cuz she just lost her job.
