If you experience a whistle noise after installing any upgraded air filter, induction kit or when using a calibration that increases power output such as Maxd-Out, the Pumaspeed Racing sound suppressor is for you.
The Focus RS Mk3 produces some incredible noises, but some cars also suffer from a whistle on cold start or during light throttle openings. As airflow and power output is increased through larger induction kits and mapping, this noise becomes louder meaning cars that seemingly didn't whistle, appear to, often incorrectly diagnosed to the part that's increasing the airflow.
This noise itself is the byproduct of the air passing through the compressor housing of the turbocharger, it's the same basic principle as the noise heard when blowing across the top of a bottle.
The Pumaspeed Racing sound suppressor replaces the resonator found on the stock turbocharger and can be installed within an hour.
