Where's 31st330i? :D

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.
ic ic .....someone's selling a 330i exhaust...muffler....(not the whole system)



do u think its worth it ? ....going price is $25 No Reserve






and man....one day.... i wanna be able to answer questions like u guys =)
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?
