The factory muffler has perforated chambers to reduce intake noise during hard acceleration. This presented an opportunity for improvement, both in terms of performance and 'intake sounds'. For the performance minded MINI owner, the muffler delete pipe will improve flow into the turbo with a side benefit of being able to hear the turbo 'whine' and bypass valve a little louder - these are cool sounds without being obnoxious.
Proper design prevents the hoses from slipping off the ends.
Another side benefit from our muffler delete pipe is that less turbulence means less heat. Less heat means a cooler more dense air charge resulting in more power.
For the following MINIs:
2007+ R56 MINI Cooper S Hatchback
2008+ R55 MINI Cooper S Clubman
2009+ R57 MINI Cooper S Convertibles
NOTE: Although the factory clamps can be re-used, installation will go 'easier' if you replace with the common 'screw type' hose clamps. Clamps not included.
