BMW 328i E46.
 

Hi guys! Excuse me if this message does not go in this forum but I'm a bit new in this :roll: . Well, I'm gonna ask you about BMW, exactly about the 328i model (saloon) 192 bhp?. My doubt is this one: Some time ago I saw one 328 E46 with an exhaust system I've never seen before. It was really interesting as in one of the two exits had a lid that got opened or closed (depending on the engine's revs I think because I read something about it in a car magazine, altough I don't remember if the exhaust belonged to a BMW or to another brand). But a friend of mine says that it is impossible that I could see this in an E46 model because this system was only used in E36 series, concretely in 328 and 323ti (compact).
I perfectly difference E46 from E36 of course :D , but I want to convince him of what I saw was really what I'm saying to him, because if not I'm gonna seem a lier :shock: .
Please, can you confirm me that what I saw in the exhaust was real and not fiction :D ?
Thanks. Regards.

Okay, the E46 328i was a carry over from the E36 328i/is models. This happened only in the model year 1999 and 2000. The new 330i and 330ci was introduced in 2001 and 2002 respectively.

So to answer your question, is that I am not sure. =). I wouldn't be surprise if BMW just carried over the entire exhaust system as well as the engine to the E46 for the first two years.

anything is possible - if it was an aftermarket exhaust :wink:

My friend had an E46 328Ci a couple of years ago and it's not the same engine as in the E36 328.

E36 328 = 193bhp @ 5300rpm and 280Nm @ 3950rpm

E46 328 = 193bhp @ 5500rpm and 280Nm @ 3500rpm

I'm not completetely sure but I don't think that the E36 has the Double Vanos system that the E46 has.

[quote="Ghostbat"]The M3 E36 had it :) . So it's possible.

to my knowledge, all E46 3-series have that flap in one of the exhaust tips that opens and closes to provide optimal backpressure to the engine for a good torque curve. I'm 100% sure that at least all '03 and newer 3-series have that standard.

Hmmm, that could be as simple as ECU tuning.

More research, be back soon.

Have you found anything about it?

Sorry, been busy. But I'll try to find out something this week. Will let you know.
