I am wondering what mods need to be made to put the Corsa exhaust kit for the '99 and up Seville and Deville on the '97 Seville STS. I was talking to Jim Browning Jr and he said it was possible with some modification. If anyone has any idea what mods need to be made let me know. I dont want to have to add some crappy aluminized conversion pipes into the all stainless exhaust kit. Thanks.
