Q: How much weight will the M Performance Exhaust save over the factory setup?
A: No figures yet because still in preproduction form.
[From Jason: the pictured exhaust is still preproduction so the final production exhaust may look different. Also, the exhaust is constructed from stainless steel, so don't expect much weight savings over factory. The focus is on sound improvement (and aesthetics) with this exhaust. The choice of stainless steel was made with the M2's price segment in mind].

Q: Any power gains from the M Performance Exhaust?
A: Few gains should be expected just from changing axle back exhaust on a turbocharged BMW because 1) the main restrictions are in the two catalytic converters, which are retained with an axle-back exhaust and 2) no gains should be expected without remapping the ECU because the ECU is always correcting, so for example if the car loses backpressure, the ECU will reduce power.

Q: How do valves operate on the M Performance Exhaust?
A: Valves are solely driver-controlled using an included bluetooth remote (see photo of exhaust remote from a MINI, which the M2 remote will resemble). The exhaust valves do not automatically open or close at a certain RPM.
[From Jason: the remote may come in packaging which should fit in the cupholder to act conveniently as a remote holder].

Q: Does the M2 M Performance Exhaust use the same tips as the M3/M4 MPP exhaust?
A: Yes, they are interchangeable.

Q: When will the M2 parts be available?
A: The goal is for them to be available at launch, in April.
