Exhaust

May have been asked and answered already but I haven't seen a thread on this yet:

What's the difference between the exhausts on the various E90's?

I can tell there's a difference in sound between 325's and 330's. Is there a difference in sound between sport and non-sport too?

Are some exhausts larger and/or more free-flowing than others?

To me, the engine note is one of the big influencers on buying a car. My E46 has little/none of it, except under full throttle; so I'm looking forward to "hearing" a little more out of E90 - which is in production this week BTW.

Thanks.

i dont know the difference in performance, but the 330 comes standard with the chrome tip. i also notice there is some kind of sensor in one of the tail pipe for the 330. is this related to performance in anyway???

It opens and closes to adjust the exhaust flow

Very little difference between the 2

Euro exhaust is different and unique to each model

Sport pack makes no difference to the exhaust
