Hello,

I am purchasing a 2011 328i xDrive M-Sport with the N51 motor...does this matter? I want to know what the best intakes are out there for a refined and better sounding exhaust note.

Will an intake even improve the sound of my exhaust note? I like the swirling noise from cold air intakes but do not know where to look or where to start.
Or would I be better off saving up for the BMW performance exhaust?

Intakes won't really affect the exhaust note. Ideally you're going to want to start messing with your exhaust to do that. But as far as intakes go, it's a generally accepted thing on this forum that these stock air boxes are the best for these cars. Now if you're going for just sound then a cold air will do, and since most cold air intakes on these cars actually hurt performance, your best bet is to just go for whatever one you like and fits your budget.

There are a few intakes out there for the n51/2 that slightly add power but they're pricey if I'm not mistaken.

intake won't do anything but if you do get one get the euro air intake for ease of getting into filter

I'm asking for noise.. I've heard there are numerous intakes that increase the sound quality and nobody will actually link a d**n intake that sounds good.

So Intake is really only for noise? Even a cold air intake?! I thought a CAI or a DCI would be an upgrade from the stock intake... Especially when combined with inlets n other things. So Stock intake is the best from what I am gathering ...

Some do gain power. I already answered the OPs question on our side of the forum, apparently he didn't like the answer.

Another option is Injen, but honestly sound is subjective - so there you go.

Injen for sound for sure
