Couple issues- Vacuum or Exhaust leak?
 

Hi all,
Hope I'm not a bother with this but I've been struggling with my R56 6MT. Sounds like it's gotten worse. Been struggling with a misfire code + oil issue. These are known based of P0341 (P0341 OBD-II Trouble Code: Camshaft Position Sensor Circuit Range/Performance) and oil light comes on during hard braking and cornering, no sign of leak tho. What I am worried about is how the engine/exhaust sounds. Hope you guys can take a listen and help me out. If, not don't worry.
