Bimodal Axle back for N54 135i

[thezone135i]

After many aftermarket systems on previous cars I have decided to not ruin my N54 with racing exhausts that never go away. I like the sound of the stock exhaust except for:

1) It could be a little deeper at idle (but not louder)
2) It could be a little louder at WOT.

I'm not after any gains as I'm happy with the power Ive got so it got me thinking maybe there's an after market "bimodal" type solution for this that will just make it sound a little better.

I'm guessing everyone will say BMWPE but I'm thinking this may not be all that subtle at idle, there must be a better product that this out there?

I have the Meisterschaft GT and it was actually disappointingly quiet to me considering how loud the Meisterschaft is on the 1M and 335i - but that could because of the great sound deadening in our cars also.

Therefore, it might be the exhaust for you if you want something slightly louder

Sounds interesting where do I source one from? Rough $$?

I ran straight mids ( mid cats and resonator delete ) with the oem axle back when I had my 135i and it sounded awesome..

I'm very happy with the sound of the stock exhaust with catless downpipes. Would be nice if the pops and crackles were a bit louder but its something I would definitely want switched with a valve.

I have a map with the Procede tune that forces the wastegates open (means no boost pressure though ) and that makes a wonderfully loud exhaust sound. You get massively loud pops and crackles on rev matches. If it was possible to get that kind of sound with a remote flap that would be awesome.
