I was reading on the aps website about how greath they say it is but I am wondering if anyone has any first hand experience with this particular up pipe. If so, is it good or is it bad, how is it compared to the helix or the vishnu one? I don't mean to bring forth questions that have been answered in other threads, just curious about this particular one.
