Pulling the fuse will leave the NPP open all the time, that's what I did. So it won't close up at cruise speeds. Stainless Works long tubes come with the x-pipe you mention, mine go all the way back to the NPP muffler. You're not bypassing the NPP exactly, but instead just using it for the loud setting and disabling the valves so it STAYS in loud mode. In my opinion, keep the NPP and get the Stainless Works headers, pull the NPP fuse and enjoy. If you swap NPP for another exhaust, you're just spending extra money when it isn't necessary.
