Well on the Hooker website they applications all say softails, and this picture of a Heritage with them on would make me think they will fit a Deluxe no problem. This pic is from the Hooker web site.
I've got Fourbiddens (Darksides) on my 97 right now. They're louder than the Big Radius 2-into-2s that I had, and put out a little more heat around the leg area. I still prefer my Pro Pipe for for overall looks and performance. I've never seen a Deluxe with these pipes. Post pics when you get them on.
