As Scott said, I'd just sell it. I have power losses under 4k with my M&M catless x-pipe, but I love the sound everywhere and the gains above 4k really make it worth wringing it out to 7k vs short shifting and just riding the mid range. If you don't love the sound of yours, I'd just drop it for 200 cell crossovers. I had some NHP 200 cells from Maxspeed and was very happy with them and the mid-range power/torque. Combined with fister modded cans, they sound really nice too. I just like the x-pipe sound and top-end better at the moment.
