Madness MINI Cooper S R56 Intercooler Muffler Delete Pipe

When Madness found this part on the new R56 MINI Cooper S we couldn't figure out what this was. After doing some research we discovered that this was an intercooler sound muffler. Personally we think the MINI needs more volume not less. When we removed this piece, we disected it and found many chambers used to baffle the exhaust volume. A negative effect of this design is that it creates a lot of turbulence as the charged air passes through the muffler. This in turn slows down airflow in this area allowing volume to be absorbed in the chambers and also increases heat.

By replacing your factory intercooler muffler with our delete pipe, quicker boost responce can be acheived and also slightly more turbo volume can be heard. Another side benifit 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. Using our Intercooler muffler delete pipe we recorded 3-5 degrees temperature drop on the pre-intercooler pressures.
