Hi MR,
I have M2c with OPF.
What is a solution for a better exhaust sound?
so that the exhaust:
- has civilized nice sound and not wild screaming
- is drone free (Drone is so typical for aftermarket exhaust solutions at mid revs)
- enables to keep the factory warranty for the car (no ECU tuning possible as a result)
The noise level or any emission standards are not an issue as the car will be used outside the European Union.
Would factory M performance exhaust be the right solution? Or it can’t be paired with the OPF exhaust so that it is not throwing the error message?
Would the Akrapovic slip-on be a good alternative solution? Will it work with OPF?
