Supersprint have been quite busy developing a full exhaust system for two of BMW’s models, the F10 M5 and F12 M6. Their aim for this project was to improve performance, looks and sound without making any compromise.
Now they have released full specs of the exhaust with pictures and video, and it seems each segment of the exhaust has several options, giving each owner the chance to customize it.
First off, you can get 2 options of the system with a catalytic converter and one without. The first catted version features the converter on the front pipes. As the system throws off the O2 sensor, a check engine LED will appear on your dashboard, so this version is best used with a ECU upgrade that removes said light. If you don’t desire the ECU upgrade, Supersprint can also provide a solution.
On the second version, the catalytic converter was fitted on the downpipes. This option will not throw off the sensors, and it will still improve the air flow through the engine. The downpipes can go together with either resonating or non-resonating front pipes.
Finally, you can get the exhaust system without a catalytic converter. This is the version to choose if you don’t really care for CO2 and want to get the most out of Supersprint’s creation. Again, you might want to get rid of the O2 sensors issue, and you either opt for the Supersprint solution (using microcats) or by deactivating it with an ECU upgrade.
The center segment of the exhaust comes with or without an X pipe. Depending on this choice, your F10 M5 will play a different tune. At the end of the system, you have the choice of three mufflers: Sport, Race and Valved.
