BMW F10/12/13 M5/M6 axle back titanium exhaust with valves
This TiTek axleback was made to work with both the BMW F10 M5 along with the M6 F12/13. From the R&D carried out by SP Engineering, it was noted that a full cat back system on the new turbo V8 model BMWs was not changing the level of power on the vehicle. The OE system was well designed and changing the entire system did not come as necessary. Rather instead, building an axle back exhaust with a proper exhaust note for these grand touring vehicles seemed to be the correct choice. This exhaust comes with butterfly valves to work in conjunction with the OE system.
