If my 2003 GT didn't have the humps in the rear bumper for the exhaust tips, I'd be running dumps. Gives the deepest exhaust note and is earth shaking.
I have Magnaflow o/r x, borla c/b with welded in Pypes M80's. I freaking hate it. Real raspy and from 3 to 5 grand, it will split your ears and make them bleed.
