I don't think an x-pipe is going to help much but it will change the sound a little.
I only feel a very small dip in the low end, in the top end it seems to pull a bit harder. But that's only my butt dyno. That low end dip seems to be common with the akra as well, and a good tune can fix it it, so I might try that.

The small dip in the low end could be more noticeable the DCT which is not the smoothest at low speed to begin with. I see that you have a manual, and with the manual it might be less noticeable.
