ExhaustI have the Stock Exhaust but wondering if it's possible to swap it out for the performance exhaust?

Late 2016 model and i have a blank button on the centre console where the PE button could fit if i were to retrofit.

Doea anyone know can it be done? If so, cost approx? If not, what isnbeat alternative?

Alternatives are Armytrix, FI Exhaust, and Logos Engineering. Logos Engineering posts here, but they haven't yet released their exhaust. If their downpipes are any indication, their exhaust may be cheaper than the first two. https://mbworld.org/forums/c450-c43-...l-exhaust.html

You'll definitely pay some serious money for refitting a PE exhaust. Unless you just have to have one, I think I would choose one of the aftermarket options.

I somewhat did this. I had c43 performance exhaust mufflers hooked up to a c63s mid-pipe section. The parts are expensive, even used. I paid $2000 for mufflers and mids, I could only source a used c63s mid.

Purchasing new from Mercedes is around $4k from memory. My dealership would not install it. Hooking up the button also requires a new wiring harness and is essentially not going to happen.

I ended up using a 3rd party valve controller for the flaps.

It certainly can be but like others here said, it is costly, if you are still interested, here is the thread where the OP successfully performed the operation:
