Where's 31st330i?

I'm sure he can explain it far better, but my understanding is the 330 exhaust is basically straight pipes, and is a dual exhaust system. 1 pipe has vacuum actuated valve which is closed at low speeds, and opens at higher speeds. The other pipe is open all the time.

Not sure. Someone else can probably answer this better.

it would be interesting to install it on your car. I bet it would make an incremental improvement. you'd need to have a muffler shop weld it on using a reverse Y collector because you have a single exhaust and the 325/330 muflers ahve dual inlets.

One thing I noticed is that MY car has the exhaust valve... Do the 325xis get the 330 exhaust. or is this a fluke like the automatic diffs on some manual 330s?
