wildcat exhaust

hey im posting this for a couple friends, one has a 94 wildcat 700efi and one is trying to buy a 93 of the same and they were wondering what is available as far as aftermarket cans for the exhaust. nothing loud just lighter weight and a little more power. i saw that d&d makes one for 95-96 wildcats, what would be different about these from the 93-94 wildcats? any help is appreciated. thanks
