06SE_Shee. I have only used stock pipes, Toomey T5´s, A&S and Power Pro drag pipes, so my opinion is next to nothing.
BUT, please - do a small and fast search about pipes. All info you need to know is in this forum, no need to find anything special top secret shit anywhere else.
Almost every pipe will work with your stock un ported motor, but you need to think where you want that power to be at it´s BEST.
(sorry my english)
