I went and had a look at that car when it was for sale. As I was taking it for a test drive I saw another M325i parked at a mechanic. After the test drive I went and had a look at the one I saw during the test drive and the owner happened to be collecting it as I was looking. Long story short, I ended up buying the one I saw while driving (now) your car.
You planning on converting back to full mtech 1?
Regarding exhaust, no I haven't got any idea what i'm going to do with it. Sorting other stuff first. Would like the original exhaust that the car came with but I believe they are near impossible to obtain.
