M3 v8 induction noise

[Lefty]

I was fortunate enough to get a drive of a CSL today, I knew they sounded good but I wasn't prepared for quite how extraordinary they sound from inside, especially with the flap mod!

I've got a v8 m3 which, in comparison, sounds awfully tame and civilised. I'm aware there are a variety of induction kits available, from simple filter swaps at £60 for BMC/K&N all the way up to full carbon plenums/air boxes at £1500-3000. Does anyone have any experience of the different options?

Will any of them come close to the intoxicating CSL induction roar?

Cheers,
Lefty

I remember reading that evolve had put the e92 v8 air box on hold, as the original air box was so efficient.

Thanks all. Yes I read about that too but I see they do sell the Gruppe M air box...
