I managed to get the Remus fitted over the weekend, nothing overly complicated, some brackets and hangers put on the wrong way as the instructions are pretty useless, but got there in the end. 2 people definitely required at some point when trying to get the new box fitted up.
Marked off at the dimple on the pipe
Stock muffler is substantial in size compared to the Remus, but if felt lighter than the Remus
Fitted up and aligned reasonably straight
The M5 style diffuser though seems a tad too small to clear the whopper 4 inch quad tip setup, i couldnt get the alignment right where was no rubbing, the outer tips are in contact with the outer edge of the diffuser on both sides, i cant see any left/right adjustment on it, only up and down. Ive ordered a 550i diffuser from local BMW dealer
First attempt:
Slightly better but rubbing:
Out for test drive and a quick sound check, sounds pretty good, im glad i didnt get the cat back as that would be too loud with the VRSF sports cat id say:
Smell of burning plastic so rocking the dual setup for a couple of days until 550i diffuser arrives.
