Custom X pipe enquiry.
Hello guys, i own a 2014 C63 with the Performance Package Plus. I wanted to know what to tell the custom x pipe makers to do, I mean shall they remove before the noise resonators or after. Any one can link a post or at least tell me how did they do it.
Many Thanks.
Many Thanks.

Most people are replacing the second set of cats with an x-pipe, h-pipe or straight pipes. Then if you want it louder still replace the resonator with straight pipes.
Search the site a little as there is tons of posts and opinions about this.

All other things being equal, a properly designed X-pipe will make the car QUIETER, not louder. If you replace the cats then that's the source of the increased volume, not the X-pipe itself. The purpose of an X-pipe is to aid in exhaust gas scavenging, which minimizes the pressure differential between the exhaust gas pulses coming out of the enhaust, making it quieter.
There are X-pipes that are "for show", and then there are X-pipes where some math goes into the actual positioning and design like the angle and diameter of the "X" etc. so that the high gas pressure pulse from one bank of cylinders will be "sucked" and aided by the low pressure from the previous pulse from the other cylinder bank going out. Unless you know what you're doing, I would sugest buying a pre-fabricated one from a reputable exhaust manufacturer who has taken the various variables into the equation and built a pipe that actually aids in exhaust gas scavenging. If the X-pipe on its own makes your engine sound louder instead of quieter, it is doing the opposite of what it's spupposed to do and is actually robbing you of power.
