M4 ZCP Muffler PN# 18307851179
M4 CS Muffler PN# 18308074086

I wonder if we can fit M3/M4 ZCP or CS muffler on the M2C. Assuming some cutting is done successfully, would the tips align just like OEM muffler does? In other words, I think it would be nice to know if the distance between the two pairs of tips are the same (stock M2C muffler vs M3/M4 CS/ZCP muffler).

I believe the M2C muffler/exhaust will likely be similar to the M4 comp exhaust without much difference. I know the guys that out a ZCP on a normal M3 said it sounded worse than before. I think with the ZCP exhaust, it's all about the tune. Although from the exhaust clips that have come out for the M2C it sounds very close if not identical to the M4 ZCP.

The M4 MPE exhaust tho, that is a thing of beauty. If the the M2C MPE is the same, that would be my first choice. The CS exhaust I think will suffer the same issues as the ZCP on a non-ZCP car, i.e. sounds good if it has the CS tune.

I have MPE on my M4 Comp and I love it. I might do the same on M2C but MPE is pretty costly. I'm sure the stock ZCP muffler would sound almost identical on M2C. However, the main reaaon I wanna do this swap is not because of the sound. I just want to get rid of that huge ass muffler on M2C. If I could fit stock M4 ZCP muffler with AA midpipe on M2C, I'd be pretty happy.

I wonder if I could just swap the CS muffler in place of my ZCP one.
