Oh, one more important note about adding an X-pipe. You are much more apt to get the annoying drone (1900-2100 rpms) with the X-pipe. I had it bad with my Maggie catback but my Steeda produces very little drone. So it does vary between systems. Again, my strong advice is to NOT get the X-pipe until you've tried the catback only for awhile. If you're satisfied leave it alone and spend your hard-earned money on other mods. If you want to change the tone then add the X-pipe at that point. But be prepared for possible enhanced droning with the X-pipe.
