First off, I’ll apologise in advance because I know this question would have been asked thousands of times - but I just can’t find the answer even after searching!

I’m looking to purchase a BMWP exhaust for my E92 325i (N53), but preferably second hand to save the pennies. My questions are:

1) Will a 330i exhaust fit?
2) Are the fittings on a manual and automatic the same (as some sites selling them new appear to specify for automatics)?

Many thanks.

Transmission doesn't matter.

I believe the parts are all interchangeable between 330/325/328 N/A motors, regardless of transmission. However, be advised that the exhaust system for the SEDAN (E90) is actually a few inches SHORTER than the systems designed for coupes and convertibles (E92/E93). I believe the extra length is just in the actual muffler/silencer tips, so you can use the longer coupe/conv. system on sedans, but the tips will stick out a few more inches unless you cut them off, shorten them, and weld them back on (assuming that's possible). To each his own there...

Brilliant, all of that is exactly what I was hoping! Thanks for the replies!

The 330i version has a open/close flap connected to the exhaust. The 325i version doesn't have it. I think it makes the 330i version quieter at low speeds and cold starts

Is that on the PE or stock exhaust? I believe the 330i does have the exhaust flap on the stock exhaust but I could be wrong.

Both. My n53 PE has a flap in one of the exhaust pipes just as my standard exhaust did
