Keep in mind that it deletes the stock exhaust so essentially you're paying the marginal increase for the MPE over what the stock exhaust would cost.
This works out well for those that want to get rid of their OEM exhaust and put on the MPE and never worry about it. However, for those that wanted to sell the MPE at some point and swap to a different exhaust or sell the car, you'd have to look for a replacement exhaust in the meantime.
Side note ...
I saw that they put up the individual interiors on the BMW Canada online configurator as well
. Pretty sweet but essentially $2,000 more than the cost of the regular full leather offerings.
