Guys, Thanks for the response, I would prefer somthing that is a bolt on. I dont really need a full exhaust even half would be fine. I spoke with Ticher from the US and they didnt have a BMW part number for PE exhuast that supports 325i with N52 engine.
If any one else has any other info would be great
Might have a look at Remus and see what its like thanks for the info bmwaddiction.
