Description Reviews WMW Noise Maker Delete Pipe for 2007-2010 MINI Cooper S (R55, R56, R57, N14 Engine). If you look at the intake hose coming across the N14 engine going down to the throttle body you will see a small one inch diameter hose coming off of it going under the intake. Well this small hose bleed intake pressure (boost) to the noise maker for more engine sound inside the cabin. This in our opinion this is a waste of intake boost which reduces horse power. The WMW noise maker delete pipe is an aluminum machined pipe that directly replaces the plastic pipe with the noise maker hose. This pipe is is machined to fit the stock rubber hose on the bottom, going to the throttle body, and fits the aluminum fitting on the top rubber hose clipping and locking into place exactly like the stock part. You will reuse the stock locking clip. Black anodized for long life and a stealth look.Note: Sold as individual noise maker delete.
