Which 340i DP+exhaust setups yield spooling noise ?

One of the things I miss from the 335i is that the turbo spooling sound was more pronounced in the exhaust note. The acoustic harmony of the high-pitched spool combined with the beefy, throaty exhaust is one of my favorite sounds.

Which downpipes and/or exhaust systems for the 340i yield a good spooling sound from the exhaust?

I think an Intake would be a cheaper place to start if you want to increase turbo spool sound. Or you could always get a bigger turbo.

Intake and catless DP = turbo spooling heaven!

Any catless downpipe would do it, like Evolution Racewerks.

For more sound, there aren't too many exhaust out but AWE is one of the nicest.
