BMW 440i grand coupe m performance rear silencer

[James76]

Hi,
I'm trying to find out if anyone has fitted just a rear m performance silencer to a 340i /440i.
I didn't know weather it will make a big difference, I've seen videos on the mppk system but not of the rear silencer only I think they call this the mpe.
If anyone has one could you let me know if it's worth spending the money on this.

Cheers james

Not a 440i, but I had the MPE fitted to my 435iGC and IMO it's WAY better than the stock item. I find it has the perfect growl and doesn't drone. No performance upgrade in it as it's only the back, but worth it for the sound IMO.
