Is there an easy way to reduce drone in my 718 GT4 / Spyder/ GTS?

Yes, actually, there is! You can quickly cap off your sound symposer – a built in system which pipes engine sound into your car. When running aftermarket exhaust components you may find you no longer desire this effect. We sell a sound symposer cap kit which can be installed in around an hour and is easily reversible.
