Milltek Header w/ Test Pipe

Milltek Header w/ Test Pipe for MINI Cooper S

Traditionally thought of as a downpipe. The stock manifold/downpipe/cat is the biggest bottleneck in your exhaust system. An easy bolt-on installation that comes with all needed hardware & gaskets that need replacing. Removes all cats for highest flow. Can be installed with your stock exhaust or with a Milltek Sport unit (or any other aftermarket exhaust). This header will cause a check engine light of P0420 due to no cats and is designed for off road use. Car needs to be tuned to take full advantage of  the performance and to turn off the check engine light.  May not be legal in some states, will also make the car very loud depending on what exhaust you already have. Comes with all needed gaskets, and normally you can reuse the gasket from manifold to head, but we do have that gasket separately. Gasket Link

Note: You will get a P0425 Cat Code (Check Engine Light) until the car is tuned. It will also be really loud...!!

Note: Not legal for on road use or use in California. For off road use only.
