**Z4 Fitment**
The headers will fit the engine but one flange on either the header or your stock midpipe will need to be modified slightly. Any shop should be able to easily handle this. One flange will need to be cut off and rewelded after being turned 45 degrees. A few of our customers have done this with no issue.
