Hi All,

First post here, Looking for a bit of help/guidance. Having an issue with E60 exhaust. It's a bit of a strange one. Got the backbox taken out a put in a straight pipe with an original exhaust tip. The car is running perfectly but after driving on car for a while the noise (RPM 1500/2000) the exhaust seems to change. Sounds like a blown exhaust/drone noise on low RPM (Very loud). Noise can stay in the car for a long time or can vanish after 10 minutes and the car will sound healthy again. The change in the exhaust noise can appear in the car at any time and vanish at any time.
EGR also recently changed.

Thanks for the help.
