Z4MR... lacking... drama?

This is an odd post to write, but I wanted to see if anyone shared the feeling I have that the Z4M lacks some drama in the noise department?

Of course, it's a sophisticated car, but I was expecting a bit more, how do I say, aural excitement? Mine is stock and even with the roof down, while it sounds nice, it's also a bit... dull?

Do intake/exhaust upgrades help much (I'm a BMW novice) or are these cars set up pretty much as good as they're going to get, from the factory?

Opinions welcomed, advice even more so (unless the advice is "Sell it and buy a Scooby you chav" in which case, I've had it already :)).
 
I've just come from a TVR so I do find it quiet.. but, I quite like the exhaust note that the 3.2 produces, certainly not TVR territory, but a lot more suited to touring. Saying that, when you do put the hammer down I find it has a nice growl to it..
 
I loved the way the S54 rasp builds to a scream through the stock system when I first bought the ///M, but I also found it lacked a little presence.
I've recently changed the backboxes to Remus and it's transformed the whole experience without any intrusive drone on the motorway or sounding / looking chavvy :thumbsup:
Others have RPI or Supersprint systems which are somewhat louder (especially the RPI race) but apparently can be intrusive on long journeys. Each to their own I supppose.
 
Blame the EU regs around noise pollution for dampening down the car's voice. TVR/Caterham/Radical and the like get/got away with it due to the small volumes they produced, which meant they were subject to a less stringent testing regime.

Race cats, different intake, gutted silencers (or aftermarket ones) can make it sound much better/louder.

How does one go about gutting one's silencers?

You split the silencer, remove the baffles, weld the silencer back up.

Not a very nice sound usually though.
 
There is a detailed post on here detailing an exhaust mod that costs less than £100 and works fantastically. It basically runs a pipe that lets some of the exhausts gases bypass the silencer. Retains OEM look but you get a much better soundtrack :thumbsup:

I would give you a link to the post but for some reason I always struggle to find / search for posts on here :cry:
 
Here it is. Good cheap mod by looks of it...
