Hallo...
Sorry have to write in English.
Do any of you know why the Americans gets there Performance Auspuff with a MSD?
And if they have a 328i they get the rear muffler without the valve that the 330i euro has.
The solution to us with the 325i N52B25 engines, must be to order the Performance Auspuff that they do...
Yes I know it doesn´t have TÜV, but we doesn´t get it either if we install an Euro Performance Auspuff from a 330i.
Like you can see here...
