Time to do the exhaust mods. Super easy on z4! Need to buy 1 1/8"rubber vacuum hose cap. You can find them just about anywhere. Just above the right exhaust tip is the exhaust valve. Remove the s-shaped hose and put a cap on the end of the hose that remains.

Yes the new update also reprogrammed the ecu. The recall that was performed was to reduce the speed you can raise and lower the top at.
