Default More supercharger noise

Hi guys,

While I am quite pleased with the stock exhaust noise, especially with the VAP pulley tune that adds crackles on the overrun, I did want to hear a bit more supercharger induction whine, and here’s what I did:
-remove engine cover;
-remove hood liner;
-replace stock air filters with BMC competition air filters (OEM air filters on Porsche GT RS series cars)
-remove carbon filters in the upper part of the air boxes (these clean out hydro carbons in the blow back from the crankcase vent system on engine shut off). Engine cover and hoodliner removed
BMC airfilter in place, note carbon blow back filter in upper air box part
Carbon blow back filter removed
The removed OEM paper air filters and carbon blow back filters
The end result is this:

Its a short iPhone recording, windows closed. The volume of the high pitched supercharger whine has increased quite a bit, without resorting to cutting resonators on the intake tubes. I love the end result of these simple mods.

It is. I've ordered BMC filters for my F Type and will see how that goes.
