I know there are a lot of exhaust threads on here, but I could not find the info I was looking for on the Kuryakyn Crusher Slip Stream or the V&H Trike Deluxe slip-on mufflers. Do I need the trike exhaust adaptor kit for either of these? I believe the V&H Deluxe do not need the kit since these mufflers were made for trikes, but I wasn't sure if the Crusher Slip-ons need the kit. Some vendor sites that sell these state you do need the kit, some sites do not mention needing the kit at all. Any one out there run either of these slip-ons on their Tri-glide?
