I ordered my Estroil Blue 6 speed manual m sport packaged 228i and i am currently waiting for it. I have the following question, ones i take delivery should i wait until after the break in period to install the M235 mpe i have planned to install on my 228i or can i install it within the break in period?

I have a feeling it will be fine to install it within the break in period because it is a port install option but at the same time i dont want to risk it if theres is a potential risk. Any comments pros or cons will be greatly appreciated.

Yes you can install it during your break in period. The Manual just says not to go above 4.5k rpm and 100mph for the first 1200 miles. Some people, like myself, follow this while others don't. To each their own.

You won't be doing anything that will harm the engine during the break in period by replacing the catback, which is all the MPE really is. Just know the pipe sizes will be different and that will require some modification. But other than that no effect. I'm almost 100% sure. But I'm also sure that there will be some sniper on this forum to come in and contradict everything I just said because they are, well trolls. But put simply no issues that effect your break in period. You are correct to point out that it is a port installed product for the M235i.

Thanks a lot for the reply. Thats exactly what i thought but was looking for some confirmation. And yes i am aware of the piping difference between the M235i and 228i, but that shouldn't be a problem since i am taking it to an exhaust fabricator for install. Thanks a lot for the reply again.

No worries. Post pics and videos after install! Good luck

Should be fine.
At least once your car is broken in, the exhaust is too!

The difference between them is that the 228i pipe is 75mm and the MPE from the M235i is 80mm but apart from thats its not much. Nothing that an exhaust shop wont be able to handle, you might have to cut it length wise a bit and well accommodate for the size difference but it should be pretty straight forward and simple.
