i had an 04 gt... always ate up the outside edge of the tires.... see it a lot on mustangs. might be the norm. my 07 even chops the outsides a bit :( cant do anything to fix it.
the only reason i have the cats is for inspection and cutting away from the raspy x-pipe. behind the x was the easiest spot for them, and it ended up sounding awesome. :D
