re: Is this considered to be a Rev pipe or a Torque pipe?
The names, descriptors, monickers mean squat. There's burly, there's gnarly, there's mountain, desert, woods and whatever else.
If it's a -30 it's a rev profile
If it's a -35 it's a torque profile
Both profiles fit both kdxs (referring to later model 'H' bikes). Both have the same type effect on both kdxs....regardless of what any catalog says, calls it or how reference is made to it. (no grammar checking, please!)
The fatty isn't made for the 'H' model bikes.
Enjoy your new pipe!
