Monday is for M: BMW F10 M5 with Eisenmann Sport Exhaust

On this week’s edition of “Monday is for M”, we have a sampling of exhaust sounds for you to enjoy.

The first sampling features a BMW M5 with Eisenmann Sport Exhaust. The first round of revs is with the variable exhaust valves open, and then you get to hear the system with the valves closed.

The next clip is of a BMW F30 335i — yes, it’s a non-M car in a “Monday is for M” post, but the Borla ATAK exhaust system fitted to it sounds much better than the F80/F82 M3/M4. I’ll even say it’s the best sounding F30 I’ve ever heard.

For reference, here’s what Borla’s ATAK exhaust sounds like on a 2009 BMW M3. Also note how heat expands the exhaust system by about half an inch from the beginning of the video to the end.
