I have zero knowledge in this department so some insight some others would be handy
Changing the exhaust is not reccomended because during DPF burnoff, much higher EGT's are the result, and I guess they worry if a different exhaust might affect that.
Onwers manual also states to beware during DPF burnoff where you are parked, because of the higher exhaust temps coming out the back and below, that you dont start a fire anywhere.
IMO, it is not worth replacing, as mentioned, fines for DPF shutoff are massive if caught.
Im wondering if its possible to fit a different muffler for some sound, but you wouldnt want it sounding like a "ricer" would ya?
