Recently purchased a 640i convt. Would like to know if anyone has converted the exhaust to the M style. Like that look much better.
You can use realoem.com to look up part numbers and see what it shows are factory options. Either that, or see what the aftermarket offers.
Yes BMW does make exhaust for your car here is the link. http://www.shopbmwusa.com/PRODUCT/4334/BMW-M-PERFORMANCE-EXHAUST-SYSTEM
Hi - I just took delivery on a 640ix with the M free flow exhaust - I really like it. It's not outrageously loud, but it's pleasantly more growly and throaty. The tips do look nice - although they are understated - you have to look for the engraved emblem as it tucks up close under the rear fascia. Dave Tosti-Lane
Charlson89, I checked for compatibility of that BMW pm your link referred to and got an " not compatible" with 2014 640i convertible. Do you have any light on subject? Jim
From what I can tell from the website it says it will work for the 640i convert. I have seen them have this exhaust at my dealer so I know it possible.
