I'm planning on removing it because if you have dct, you'll know how shitty it is to drive before it warms up. clutch slips, power is off/on randomly SO ROUGH AND ANNOYING. Plus I don't like the sound, so rattly. This may be different if you have non stock exhaust systems installed. Main reason I want it gone is to smooth out the startup & ride. Apparently cold start causes these issues.
