Anyway even if BMW said that it is not made for that one (otherwise it is suitable for 330i and 335i with N 54 engine - this according to catalogue - and they made another one for 4 cyl. engines as well)
My 325i has the N 53 engine.
The guys who fitted my muffler said they mounted the one foreseen for 4 cyl. engines on a 125i and they had no problems with it.
I can say that, together with the BMW Performance air intake there is a sound now and I can say that I really like it. Besides that I know there is an engine in my car now i. e. I do not only feel it, I can hear it
Will let you have that code asap OK!
Bye for now
Thanks for your help with the part number. I am still unsure if it is the right one for my car. Mine is a N52 2.5 litre engine, probably the same as what is sold in Canada, but different from the USA and also different from Europe. Some online sellers in the US show a part number ending in 581, so I will try to discover if there is a difference or not. Thanks again. John.
