Hiya - Just a quick FYI. DINAN has launched the Brand New F90 ///M5 Exhaust. Here is some information about it. I will have some more details soon. I would love to be able to offer a couple of F90 Owners a special opportunity as well - that is to those who are interested in this new system.

Benefits of the Dinan F90 M5 Free Flow Exhaust:
+10 HP @ 6600 RPM, +8 FT-LB @ 6600 RPM.
Enjoyably louder, sportier sound
Four massive 4" diameter clamp-on, double-walled, black ceramic coated (or polished) and laser engraved exhaust tips.
100% 304 stainless steel construction
Larger diameter piping for increased flow (83mm vs 80mm)
Stock exhaust valve actuators reused and operation of exhaust valve is unchanged so exhaust tone can be adjusted via the M-drive settings
Computer controlled exhaust valves are retained and limit noise during low speed driving and open fully during high-load conditions.
Twin secondary exhaust valves are a whopping 76mm diameter, making them 30% less restrictive than the OE valves
Easy bolt-on installation with included mounting hardware
