Supersprint Centre Pipe (replaces stock resonator)

As an alternative to the silenced centre section 987803 Supersprint offers a "racing" pipe only version.

This component has a 75mm external diameter outlet so it's compatible with the OEM rear muffler as well as the optional "Performance" muffler.
With the stock muffler, because it's a whole with the rest of the system, it'll be necessary to cut where the small bumps have been placed by the manufacturer.
The "Performance" muffler already requires this cut, and it's provided with the correct adaptor.
For the normal muffler this adaptor can be purchased directly from BMW, spare part cod. 18 30 7 560 781

In both cases 987813 will increase the overall sound of the exhaust.

It's possibile to fit this part with the OEM front section, which is already pipe-only, but it's necessary to make another cut. The centre pipe will slide on top of the OEM front section.
To avoid the cut it's possibile to couple 987813 with 987812. The stock exhaust can be removed as a whole with this solution.
By this a re-installation back to the standard exhaust (original state) is easily feasible if needed.
