Well it's just my preference I guess, I don't feel there will be much difference with clutter either way there would be a pipe running up there either a down pipe or in this case a supply not to mention you still have to route your driver supply. And in my opinion which is just simply that I would rather have clutter out over the fenderwell and leave room for my charge pipe and bov. The compressor and altenator all suffed on top just is not appealing to me for by build. I'm happy with how it's coming out so far.
