Well. im still very confused, as some of the 335i pipes will fit our E89 and some won't. so far i know 335i before mid 09 has a shorter CP. and after 09 to 10 has a longer CP.

Anyone has any idea if this ETS CP will fit E89 N54?
Vintage, do you remember if your Stett CP was built for after or before 09 n54 motors?
