I bought the Classics for my Dyna (FXDXI) prior to my 95 build. I like the looks of the classics over the pro-pipe, however the megaphone on the Classic is too short to build sufficient back pressure for HP/trq. The pro-pipe H&S is the 3rd generation of that pipe, which has a much larger megaphone (Muffler) which is completely encased in chrome, & better header pipe heat shields to prevent bluing issues. Performance wise the Pro-pipe H&S is a result of V&H research.
If you want HP go with the H&S Pro Pipe. If you want just looks, I'll sell you my Classics (cheap), sitting in the garage.
